At present the world's industry recognized the fastest growing, more widely used the most important high-tech technology is optoelectronic technology, he will become the pillar industry of the 21st century. In the optoelectronic technology, one of its basic technology is laser technology. The development of red laser pointer technology and industry in the 21st century will support and promote high-speed, broadband, massive optical communication and network communication, and will lead to a lighting technology revolution, compact, reliable, long life, energy-saving semiconductor (LED) will dominate the market, In addition, it will launch a wide variety of optoelectronic consumer products and new information display technology products and into people's daily lives.
Laser energy measurement is one of the most basic elements in laser parameter measurement. It is very important to accurately determine the energy of the target laser to analyze and analyze the experimental data. The research of laser energy measurement is divided into four parts: the development of high sensitivity and high performance body absorption laser energy meter; the development of high precision and high stability display data acquisition instrument; the selection of green laser pointer energy measurement sampling method and the measures to improve the measurement accuracy; Data analysis and processing of laser energy measurement results. In the study of laser energy measurement, the development of laser energy meter is the key. The principle of laser energy meter is to be measured laser beam irradiation to a highly sensitive absorber into heat, and then through the circuit design to be truly measured out.
The new CF series lasers already incorporate advanced back-to-back reflection technology and a well-dispersed, retroreflective laser, stripping off the back-reflecting laser beam and providing safe consumption at the critical point of the laser by proprietary pattern stripping Scattered interference light. This sophisticated retro-reflective technology has been tested and its robustness has been proven to be more sensitive to back-reflecting laser pointer in kilowatt-class fiber amplifiers. The combination of these retroreflective protection schemes in the new CF series fiber lasers verifies its unparalleled performance in cutting and welding a wide variety of highly reflective metal materials with a thickness ranging from <0.5mm to thickness to 25mm.
The traditional chemical process, usually the reactants are mixed together, and then often need to heat (or also pressure). The disadvantage of heating is that the molecules produce irregular movements due to increased energy, which destroys the original chemical bonds and combines them into new bonds, and these irregularities destroy or create bonds that can impede the progress of the desired chemical reaction. However, if the laser to direct the chemical reaction, not only to overcome the above-mentioned irregular movement, but also to obtain greater benefits. This is because the laser carrying a highly concentrated and uniform energy, can be accurately hit the molecular key, such as the use of different wavelengths of ultraviolet laser, playing hydrogen sulfide and other molecules, change the phase difference between the two violet laser pointer beam, then control The molecular fracture process.
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 laser 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.
The application of blue laser pointer chemistry, not only to accelerate the synthesis of drugs, but also can not need to tick the side of the product, making some drugs become more secure and reliable, the price can be reduced. Another example, the use of laser control of the semiconductor, you can improve the new optical switch, thereby improving the computer and communication systems. Although the laser chemistry is still in its infancy, its prospects are bright.
