Laser Induced Graphene
According to the website of the Institute of Physics reported on July 31, 2017, the University of Rice researchers by changing the surface of the wood, so that the wood into an electrical conductor. Researchers use the laser to darken the film pattern and place it on the pine. This is a composite structure of wood and nanomaterials.
In 2014, Rice University researchers used burning laser pointer-heated polyimide sheet surface to develop a thin atomic carbon material called laser-induced graphene (LIG), a porous graphene film with a flexible surface. The film used in this technology is laser-induced graphene.
"In addition to polyimide, some wood can also produce laser-induced graphene." The study found that pine trees are more suitable than woods with low cross-linked lignocellulose content, says Professor James Thor, a professor of chemistry. Production of high quality graphene. Lignin is a composite organic polymer that forms a rigid cell wall. New technology for the preparation of laser-induced graphene has opened up new applications, such as for three-dimensional graphene printing, polyimide non-ideal substrates. In addition, the wood is also rich in reserves and renewable.
As with the use of polyimide to prepare 5mw laser pointer-induced graphene, the new technology requires the use of standard industrial lasers at room temperature and the use of inert argon or hydrogen. Because there is no oxygen, the heat generated by the laser will not ignite the pine, but will produce graphene foam corrugated sheet, and wood surface bonding. In addition, changing the laser power can also alter the chemical composition and thermal stability of the laser-induced graphene. When the laser power is 70%, the laser will produce the highest quality laser induced graphene, called "P-LIG".
Researchers have made a pair of electrocatalysts with high surface area by depositing cobalt, phosphorus, nickel and iron on laser-induced graphene, which is durable and effective to decompose water into hydrogen and oxygen. In addition, the deposition of polyaniline on green laser pointer-induced graphene can also be used as a capacitor to store energy.
There are many applications that need to be explored, for example, using laser-induced graphene integration with solar cells. We believe that this discovery will inspire scientists to think about how to develop natural materials around them into more efficient materials.

Early winter season, listening to the rain quiet meditation Jane this life feel, half from the bitter music, conform to the causal cycle of good fortune. Day cold, when the rain accompanied by music, no longer tied for the secular, take care of things outside the combing thoughts, restore my heart had a small Lan. Hurt their own people are no longer hate, no longer let it troubled life, gradually blurred in sight, dissipated in the memory. Not mention, do not feel there; mention, has been a passers-by. This is very good, flies are more important than anything else.

The Spatial Distribution of Laser Beams
Laser spatial distribution measurement is an important branch of the laser measurement system. It is mainly composed of two parts: the near field distribution of the laser beam and the far field distribution of the laser beam. With the development of laser science, the spatial distribution of violet laser pointer beam is more and more attention. In the history of the development of high power lasers, the spatial distribution of laser beams is the most important field, and its level determines the level and scale of laser devices to a great extent. Laser time measurement is mainly real-time monitoring of the final device output pulse laser waveform, each time the laser target to reach the bulls at the same time the time synchronization measurement, and ultra-short pulse test laser time measurement.
High-power lasers can produce large amounts of energy, causing some metal to evaporate. In the process of melting, the density of the steel will decrease rapidly and the volume will increase accordingly, and the movement of the material will increase, resulting in high pressure steam. At this time will produce a 'keyhole', it is the high power laser impact point on a narrow hole. The steel around the hole melts to form a pool. After the liquid steel cools, it will connect two sheets of sheet metal. The fundamental cause of most mechanical failures is the presence of defects in the weld, since the weld points are connected to different materials. If the connection is improperly handled, it will eventually cause the stress to be too large. Improper welding parameters may also cause instability of the welding point, resulting in welds in the pores, part of the penetration or undercut, resulting in the connection is not strong.
To provide customers with the right laser tailor-welded blanket, you need to choose the correct combination of welding parameters. By adjusting the grade and thickness of the steel plate in order to meet the customer to meet the vehicle crash test specifications, weight requirements and cost requirements of the burning laser tailor welded blanks. A series of process conditions are determined by simulation to ensure that defective welds are produced. Knowing the physical phenomena of these interactions and coupling them together for simulation, rather than doing multiple studies in parallel, gives us a great deal of convenience. Has been committed to helping the automotive industry to reduce the weight of the body and to ensure that the welding products have excellent quality, so as to protect the driver in the safety of driving a car.
The use of advanced high-strength pressure hardening steel, the installation of the steel plate was optimized, so that the specific area of the car to maintain the strength of the performance at the same time more thin. Ultimately, it is desirable to achieve excellent welding quality to ensure that the welding meets the safety requirements of the crash test. A safe welding can not be broken or broken during the test, otherwise the weldment will not pass the safety test. The use of laser welding of concentrated heat source will be converted into molten metal molten steel, used to form a narrow and deep weld.
Laser time synchronization (equal to the optical path) measurement, refers to the multi-beam laser synchronization to reach the target time measurement, laser pointer beam target power balance is an important guarantee. According to physical calculations, if the two beam synchronization time difference of 25 ps will lead to 10% power imbalance. And the power balance is extremely important for achieving uniform compression of the target. US LLNL laboratory synchronization accuracy requirements of 10 ps. The time synchronization accuracy of the integrated unit is 10 ps. If the infrared stripe camera is used to assist the fine adjustment and control, the synchronization accuracy can be improved. In April 2000, the highest yield of neutron production was 3.9 × 109, which was the highest level of the same kind of equipment in the first round of the direct drive experiment. The time synchronization accuracy was 6 ps.

Laser Fiber Coupler
While the market is demanding high demand from the market to reduce processing steps, reduce material waste and dry process and other factors continue to drive, is also a strong impetus to the 10mw laser pointer manufacturers and laser system integrators to provide continuous discussion, asking them not only to provide Traditional mechanical processing alternatives, but also continue to enhance the overall performance of laser processing solutions to the processing quality, product yield, processing speed and mass production has been a breakthrough.
In the processing requirements, the above-mentioned applications usually require the use of very sophisticated cutting, drilling and grooving processes on these brittle and brittle materials, which makes the traditional milling, grinding and grinding processes Of the challenge, because the material is extremely thin and very brittle, the process of application due to contact with the application of any stress on the material, may lead to material fragmentation, and ultimately scrapped. With the application of these brittle materials in products such as LEDs, smart phones, wearable equipment, etc., the laser, 50mw laser pointer systems and related research institutions that are working on such brittle materials are also increasing, and their efforts have This kind of brittle materials laser processing technology continues to develop.
If the laser retroreflective protection capability is not strong enough, even if the high power QBH or QD transport fiber designed to withstand the kilogram of retroreflective peeling off the fiber cladding, the back-emitting laser beam passes through the fiber core of the transfer line Reflected back into the fiber inside the laser. Even technology-leading fiber laser manufacturers have experienced a variety of painful lessons, system integrators have realized that the laser fiber coupler, or laser module will be damaged.
In contrast to the usual performance of third parties, and depending on the material and settings, the fiber laser has a retroreflective capability of up to 3 to 30 times the resistance due to its special optical configuration. In particular, the CF laser system incorporates these protection schemes that have demonstrated the offset error of the focal position in the millimeter scale that allows large amounts of brass and brass to be tested. Compared to other fiber 300mw laser pointer manufacturers, it shows a smaller focus position offset error; when operating a CF laser with a unique proprietary protection scheme, the reliability of the laser and the performance of almost no failure have been demonstrated.
Glass, ceramics, sapphire and other brittle non-metallic materials, precision machining, usually using ultra-fast laser. Ultrafast laser pulse duration is extremely short, in nanoseconds, picoseconds and even femtosecond, the role of moderate laser energy on the surface of the material, by breaking the material chemical bond to achieve the purpose of material removal, in this process, the laser energy It is too late to pass around the processing range, the process has ended, so the heat is almost negligible, the material does not produce thermal damage.

Why the laser TV can challenge the LCD TV
First, not the same place is the light source, laser light source life is very long, easily tens of thousands of hours to laser TV life comparable to LCD TV. Can be said that a laser TV use a three or five years is not a problem, no longer worry about the problem of light, this life cycle has been enough, after all, not all families have to use a TV for 10 years 20 years. Second, the 30mw green laser TV is a reflection of the ultra-short focus of the technology of the projector, this ultra-short focal length laser TV can be achieved within 0.5 meters distance of 100 inches of the screen. In other words, laser TV can be placed in the TV cabinet on the projection of 100 inches, in the past the projector hoisting in the middle of the living room situation gone.
These two points can be said that the fundamental advantage of laser TV, while laser TV products are constantly improving. We combined with the latest developments in the industry to talk about why the laser TV dare to challenge the LCD TV.
Laser TV is a big advantage of large size, the recent brand has released a 75-inch TV, priced at 20,000 yuan, the price is very amazing. But the laser TV can easily achieve 100 inches, and the size of the laser TV, LCD TV is not always the opponent. The price of the problem we will say, we first talk about another problem can not be ignored: the brightness problem.
Laser TV is able to achieve 100-inch screen, but the screen brightness enough? Brightness is not enough, the screen size is large, but the display is difficult to guarantee. So the brightness is not high, is a laser TV challenge a foundation of LCD. Now the 100mw laser pointer TV brightness is basically 3000 lumens. But the rapid development of laser light technology is expected in the second half of the release of new products, many began to configure a 4000 or even 5000 lumens of brightness. This brightness and then with the anti-light curtain, even if the lights to watch, the effect is also very to force. Laser TV brightness breakthrough so that this product no longer appear during the day can not be used at night must be dark paint to show the situation. So the brightness of the breakthrough is always a main line of laser TV, it is gratifying that the current laser light source brightness breakthrough faster. It is clear that the development of laser TV is not subject to brightness and stagnation.
LCD TV can also achieve 75 inches, but the product is very large, the weight is not light, coupled with handling and installation, energy consumption and other issues, it can be said that once the LCD TV size, and many problems will follow. Laser TV is different, projection 80 inches and projection 100 inches of energy consumption is the same. And the size of the blue laser pointer TV is very small, placed in the living room TV cabinet can be used, so when the installation is very simple. And with the continuous optimization of the projection chip, as well as the development of optical system, the future of the laser TV can also be smaller. Small volume of laser TV is bound to be able to adapt to more use of the environment.
At the same time the price of laser TV is declining rapidly. These days 75-inch LCD TV price of 20,000 yuan is very pleasant surprise. But according to the latest understanding of the author, the laser TV industry will soon launch a more surprising price of laser TV, the price is certainly lower than the 20,000 yuan, and to a lot lower. This new laser TV appeared, I believe that the challenge of laser TV LCD TV confidence is even more enough.
Laser TV is not only have their own table, in the content and the current smart TV no difference. Because the use of burning laser TV is the TV system, and even many TV brands are also launched laser TV. Their LCD TV and laser TV use the system is similar to the same resources to provide. So use the laser TV without worrying about no content. With the gradual enrichment of network resources, laser TV online can see a lot of high-definition content, the latest TV series, movies and entertainment programs can use the laser TV to watch. Past the projector needs a separate device, connect the player or a variety of boxes can see a large, this way OUT out. Laser TV is to see to see, do not worry about no see.
Now began to enter the laser TV market, many brands, on the one hand the brand will make more people understand the laser TV, will also let the price of laser TV; the other hand, many brands work together, laser TV this product is also the degree of improvement Will continue to improve. For example, many people are worried that before the laser TV will hurt the child's eyes, now has a brand can be introduced to the human body can function, as long as the head into the laser TV lens, the laser TV will automatically shut down. So even if the child naughty at home, it will not look directly at the eyes of the 200mw green laser situation.
Similar to the details of these optimization, is to solve the ordinary users of the use of laser TV pain points. The more brands concerned about this market, the product will be higher degree of improvement, it is no doubt. And this trend so that laser TV can gradually challenge the LCD TV.

Ultrashort Laser Pulse
Antimony inter-band cascade lasers are new semiconductor lasers based on quantum effects and band engineering. They are combined with the radiation between electrons and holes through the transition between conduction band and valence band. Each active region is connected by a similar quantum cascade Series connection. It combines the advantages of traditional semiconductor interband transition lasers and quantum cascade 30mw green laser based on subband transitions, such as uniform carrier injection, high quantum efficiency, easy wavelength regulation, threshold current density and low power consumption. Therefore, the antimicrobial inter-band cascade lasers have important application prospects in environmental monitoring, medical diagnosis and information gathering in Internet of Things, but their structure is complex and the number of epitaxial layers is large, which makes the material grow very difficult.
By using the photon amplification technique, combined with the statistical properties of the laser and the spontaneous photon, it is possible to make the angular resolution of the telescope exceed the diffraction limit. In the traditional multi-photon microscopy, the ultrashort laser pulse gathers into a close spot on the sample, stimulating the fluorescence to produce an image. And multi-photon-space frequency modulation imaging microscope is to use multiple femtosecond laser pulse at the same time illuminate the larger light area to interfere, in order to build the image.
Technology for the first time to achieve a dual-view 10 watt laser pointer scanning based on real-time stereoscopic imaging and display system, the three-dimensional imaging speed than the traditional point-by-point scanning method to improve the order of one to two orders of magnitude. In other words, the imaging process from the previous few minutes to tens of minutes is completed in a few seconds, and the two-photon stereomicroscopic imaging system provides a new observing tool for 3D real-time imaging and display of living organisms. To observe the transmission of the fleeting neural signal in the neural network. The use of an elongated focused laser beam - Bessel beam to complete the scan, through the control of the beam, you can not do light slices, a one-time will be a thick three-dimensional sample clear imaging.
The development of industrial lasers, relative to scientific applications and medical applications, the requirements of industrial processing is the most advanced. First of all, its working environment is generally more stringent, followed by the laser for a long time reliability, stability, the most stringent requirements. It is mainly used in the cutting, micromachining and non-destructive microfabrication and fine marking of transparent brittle materials. High-power green 500mw laser pointer that can be used in the PCB field are highly representative. Because of its unique high power, in the solar cell dicing, ceramic cutting, including the touch screen manufacturing process can play a lot of role.
The more representative products in the research laser are miniaturized, compact lasers and large energy lasers, mainly used in laser shock enhancement, laser radar, mass spectrometry, including spectral detection. In addition to the industrial laser in addition to the high-power, low-power picosecond lasers, this year also developed a 30-watt green nanosecond, this new laser is the most important feature of the pulse width is relatively narrow, while power Relatively high. Medical line is displayed on the trump card products: medical beauty special picosecond laser. Used in mobile phones, hardware, medical device industry MOPA pulse width adjustable fiber kids laser pointer with high precision, high processing speed, anti-high anti-technical characteristics.
For a given laser power density and material, the cutting speed is in accordance with an empirical formula. As long as the threshold is above the threshold, the cutting speed of the material is proportional to the laser power density, that is, increasing the power density can increase the cutting speed. The power density referred to here is related not only to the laser output power but also to the beam quality mode. In addition, the characteristics of the beam focusing system, that is, after focusing the spot size also has a great impact on laser cutting.
Since the laser power density has a great influence on the cutting speed, the choice of lens focal length is an important problem. After focusing the high power laser pointer beam, the spot size is proportional to the focal length of the lens. After the beam is focused by the short focal length lens, the spot size is very small and the power density at the focal point is very high, which is advantageous for cutting the material; but its disadvantage is that the depth of focus is very short, Small, generally more suitable for high-speed cutting thin materials. As the telephoto lens has a wide focal depth, as long as there is sufficient power density, more suitable for cutting thick workpiece.

Diamond Saw Blade Technology
For burning laser pointer welding of diamond saw blade, the need for appearance, microstructure and welding strength and other parameters of the test. The appearance of the main detection of the existence of welding macroscopical defects such as hole cracks, undercuts and not penetration, etc., usually need to be 100% of the detection, significant organizational detection of the main parts of the chemical parts of the inspection, significant changes in the structure and phase structure, The results show that the fine chemical composition of the molten zone has a gradient diffusion, and the transition layer hardness is lower than that of the matrix, which is higher than that of the tip. The welding strength test mainly tests the tensile strength, bending strength, impact toughness and residual stress of the weldment. It is usually necessary to carry out 100% welding strength test, and the residual stress and distribution after welding seriously affect the service life of the diamond saw blade.
At present, there are still some problems in laser welding of diamond saw blade technology, we need to carry out further research, to carry out special laser welding diamond saw carcass or transition layer material formula research, to carry out new ultra-fine or nano-alloy powder research, The research on the mechanism of 3000mw laser pointer welding of diamond saw blades, especially the research of temperature field, flow field, mass field and stress field of laser welding diamond saw blade and the on-line quality monitoring technology of laser welding diamond saw blade process are carried out. In fact, only a comprehensive understanding of the mechanism of laser welding diamond saw blade, it may be developed accordingly the new online quality monitoring technology; only master the theory of pre-alloy powder, it is possible to develop a new ultra-fine or nano-alloy powder and Better use of new ultra-fine or nano-pre-alloy powder to develop a dedicated diamond saw blade.
For large gantry laser cutting machine, to achieve high-speed, high-precision linear cutting, large arc cutting is a common technology, but to achieve a small round cut can only reduce the speed, laser cutting machine efficiency doubled. At the same time to achieve high-precision small round cutting, for large gantry cutting machine must improve the overall rigidity and dynamic performance of the machine. In order to meet the needs of special customers, a laser R & D and production of 2.5G super dynamic performance GHF-4020 high-speed high power laser pointer cutting machine. Up to 400 per minute cutting high-precision small round of the magic speed, compared to the traditional laser cutting machine can only cut 100 rounds per minute, the efficiency increased by 4 times. Its performance has been quite stable, cutting quality, cutting efficiency completely exceeded expectations.
Laser is the best way to optimize most of the existing processing technology at home and abroad. At home and abroad, after two well-known cutting and welding processes such as cutting, welding, surface treatment and cladding, The craft has done a breakdown. For example, for cutting, subdivided into melting-type cutting, vaporization-type cutting, and the melting of the cutting section of the roughness of the cutting, the vertical degree of more refined requirements, etc., which the laser and other ancillary manufacturers have put forward a new Of the high demand, so the industry is even with the integration of one of the key elements.
In the field of fiber laser, fiber lasers will further enhance the application coverage. There is also a saying that the structure of fiber lasers is to optimize the quality of direct semiconductor 1000mw green laser beam cost-effective program, so these two lasers do not conflict, but complement each other. The future In the field of metal processing, fiber laser vitality will be very strong, which may become a new trend. In terms of laser, different wavelengths, different power, different control methods of technology is the core, need a long time to layout. At this core, it is imperative to optimize the structure and technology of existing wavelengths of lasers to meet their potential needs in the current market. Such as higher average and peak power, shorter pulse width and so on.

Laser Welding Cleaning Technology
Nursing laser cleaning is divided into two categories: one is the stone and the appearance of the dust attached to a wavelength of laser energy absorption coefficient of different, so that the laser energy is fully absorbed by the dirt absorbed, and then by thermal expansion or vaporization evaporation, And vaporization of the composition of the vapor flow from the stone to achieve the purpose of cleaning. The other is the stone and the appearance of the attachment of the high powered laser pointer beam absorption coefficient is different from the laser beam is adjusted to a specific energy value, without destroying the stone surface, while the surface attachment can be high-power pulse laser shock stone surface , So that part of the beam into sound waves, sound waves in the impact of stone after the appearance of back, the return of some of the laser and the role of sound waves to form a resonance wave, so that a slight burst of crack, resulting in crushing, and thus from the stone appearance.
With laser welding and cutting process has been many years of history, but with laser cleaning stone surface is a relatively young technology. Although this process can remove all organic materials, but in the stone care process applications until recently began. I believe that with the development of laser and laser cleaning technology continues to improve, will be in a variety of cleaning areas get more and more applications.
The quality of laser cutting machine is mainly to see the quality of cutting, which is the most direct way to test the quality of equipment. For new customers, in the purchase of equipment will require look at the laser cutting machine proofing, proofing in addition to watching the cutting speed of the device, it is to look at the quality of cutting the sample. Laser cutting section will form a vertical pattern, the depth of the groove determines the roughness of the cutting surface, the more shallow the lines, the more smooth cutting section. Roughness not only affects the appearance of the edge, but also affect the friction characteristics, in most cases, the need to minimize the roughness, so the more shallow lines, the higher the quality of cutting. The verticality of the cutting edge is very important, away from the focus, the 1000mw green laser beam becomes divergent, depending on the position of the focus, the cutting is widened toward the top or bottom. The cutting edge deviates from the vertical line by a few millimeters, the more vertical the edge, the higher the cutting quality.
Cutting width. The width of the cut does not generally affect the quality of the cut, and the cut width has an important effect only when a particularly precise profile is formed inside the part, since the width of the cut determines the minimum internal meridian of the profile. The increase. So want to ensure the same high precision, no matter how much the width of the workpiece, the workpiece in the laser cutting machine processing area should be constant.
High-speed cutting thick plate, the molten metal does not appear in the vertical 3000mw laser pointer beam below the incision, but will be sprayed in the laser beam behind. As a result, the curved lines are formed at the cutting edge, and the lines follow the moving laser beam. To correct this problem, the feed rate is reduced at the end of the cutting process, and the behavior of the lines can be largely eliminated. The formation of the burrs determines a very important factor in the quality of the laser cutting, since the removal of the burrs requires additional effort, so the amount of burrs is serious and how much is able to visually determine the quality of the cutting.
The laser cutting machine first touches a special liquid with oil on the surface of the workpiece before it begins to melt and pierce. During the cutting process, due to gasification and the various materials are not used, the customer uses the wind to blow the cut, but the upward or downward discharge will also form deposition on the surface. Depression and corrosion. Depression and corrosion have an adverse effect on the surface of the cutting edge, affecting the appearance. They appear in the general should be avoided in the cutting error. Heat affected area. In 5000mw green laser cutting, the area is heated along the area near the incision. At the same time, the structure of the metal changes. For example, some metals will harden. The heat affected area refers to the depth of the area where the internal structure changes. If the cutting causes the part to drastically heat, it will deform. This is especially important in fine machining because the contours and connectors here are usually only a few millimeters wide. Control of laser power and the use of short laser pulses can reduce component heat and avoid deformation.
Laser cutting machine in the cutting process, the auxiliary gas is essential! Which we often use oxygen and nitrogen, of course, the higher the purity of the gas, the quality of cutting will be better. So, in order to achieve a better cutting effect, the requirements of the auxiliary gas is relatively high! Although the air can be used as auxiliary gas, but because the air contains water and oil, if not treated, will cause the lens pollution, cutting head instability, so that the cutting effect and quality is not compliance. Therefore, in the use of air cutting, the need for fiber burning laser pen cutting machine equipped with cold and dry machine, so that a very good solution to this problem. The cold and dry machine can be forced to cool the compressed air below the required dew point temperature, which will contain a large number of water vapor, oil mist condensed into droplets, separated by gas and liquid, discharged from the drainage machine, the compressed air drying.

With laser welding and cutting process has been many years of history, but with laser cleaning stone surface is a relatively young technology. Although this process can remove all organic materials, but in the stone care process applications until recently began. I believe that with the development of laser and laser cleaning technology continues to improve, will be in a variety of cleaning areas get more and more applications.
The quality of laser cutting machine is mainly to see the quality of cutting, which is the most direct way to test the quality of equipment. For new customers, in the purchase of equipment will require look at the laser cutting machine proofing, proofing in addition to watching the cutting speed of the device, it is to look at the quality of cutting the sample. Laser cutting section will form a vertical pattern, the depth of the groove determines the roughness of the cutting surface, the more shallow the lines, the more smooth cutting section. Roughness not only affects the appearance of the edge, but also affect the friction characteristics, in most cases, the need to minimize the roughness, so the more shallow lines, the higher the quality of cutting. The verticality of the cutting edge is very important, away from the focus, the 1000mw green laser beam becomes divergent, depending on the position of the focus, the cutting is widened toward the top or bottom. The cutting edge deviates from the vertical line by a few millimeters, the more vertical the edge, the higher the cutting quality.
