green laser pointer is a really good tool for the customer to hold a conference
China is currently engaged in high-power Nd: YAG laser R & D and production units are: Institute of Physics, Chinese Academy of Sciences, Beijing University, Huazhong University of Science and Technology, Wuhan Chutian Laser Co., Ltd.. In recent years, Beijing University of Technology in kW lamp-pumped YAG lasers have made breakthroughs in research and development, has 1 ~ 3 kw products (Figure 5) to enter the market. Fiber laser. YAG solid-state laser biggest drawback is the low electro-optical conversion efficiency, resulting in significant heat accumulation and a strong thermal lens effect. The expert is perfecting the drawing of green laser pointer .
YAG laser working substance affecting the geometry of the output power and beam quality of the important factors, for which the 3D shape of the laser medium by the one-dimensional crystal made of thin fibers. High-power fiber lasers still follow the traditional laser principle: work material for the D-type structure of special double-clad fiber; use fiber grating optical resonator; pumping system for the LD side-pumped. Figure 7 for the high-power fiber laser schematic. University of Southampton in 1987 and the U.S. Bell Labs demonstrated experimentally the feasibility of optical fiber amplifier. 1988, Snitzer and so on double-clad fiber concept. With high-power LD-pumped double-clad fiber-optic technology and practical technology, a revolutionary development of fiber lasers appeared in 2004, SPI's single U.S. double-clad fiber laser to achieve 1 kW output level.The worker has to get the material inquisition sheet of green laser pointer to fetch green laser pointer.green laser pointer can make your speech and demonstration more successful
However, there is a big drawback semiconductor lasers: laser properties. Thus, the field of semiconductor lasers in laser processing is mainly used for laser heat treatment, laser cladding, etc., suitable for laser cutting, welding, drilling, engraving and other requirements of the application of high beam quality. Its small size, light weight, can be optical fiber transmission, and easy integration with the industrial robot and so on with; easy to move, more suitable for on-site mobile operations, these areas than YAG, fiber, such as laser disc has obvious advantages. High-power semiconductor laser manufacturing technology has become in many developed countries (such as the United States, Germany, Russia, etc.) and support the important areas of China. The technicians are discussing the data on the drawing of green laser pointer .
