Germany IPG 3.2 solid state lasers are solid-state lasers in Nd: YAG laser has made three breakthroughs on the basis of the n argument developed: 1) the strip surface cooling plate rod-shaped proliferation of alternative cooling methods; conversion doped high absorption Yttrium Yb "YAG alternative low absorption material conversion Nd" YAG medium; laser diode (LD) pumping technology to replace lamp-pumped mode. Developed in Japan in 2005, the average output power of 10 kW electro-optical efficiency of greater than 20% of high-power solid-state lasers. German company Trumpf has LD-pumped 2,4.5 and 6 kW series YAG laser, beam quality, respectively 12, 16 and 25 Photonics company uses group-beam technology, Munich, Germany in 2005, the international exhibition of laser and photonics launch series of high-power fiber lasers, fiber laser marking industrial progress achieved milestones. The subfactory will implement the new working time of green laser pointer .
Fiber laser into the mainstream of industrial laser products and future trends [15 ˉ 19]. China Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, Changchun Institute of Optics and Fine Mechanics, Tsinghua University and Nankai University and other low-power laser in a stage made of experimental results. High-power fiber lasers in China's market capacity is huge, because key components are to be imported, high-power fiber lasers in China with the international advanced level falls far short of industrial high-power fiber lasers were all imported. Laser processing robot technology and light industrial applications 2785 transport structure. Outside, red to blue-green range. Generally divided into high-power semiconductor laser array-based single-tube type and two types of monolithic two-dimensional array array and stacked arrays have two, the use of laminated array output power up to 100 W, kW, or even quasi-continuous output power of megawatts or more, while the energy conversion efficiency of these devices can be up to tens of percent. The personnel in the warehouse are very careful to count green laser pointer .
In the laser processing area, there are two main aspects of semiconductor laser application [z9, 80]: I) pumped solid-state lasers: the most commonly used pump source primarily the appearance of Figure 12 HLD-4002, there are three: 808 nm wavelength semiconductor lasers for pumped Nd: YAG solid-state laser; 940 am wavelength semiconductor lasers used for pumping Yb: YAG solid-state laser, 980 rlm semiconductor lasers used for pumping erbium-doped fiber amplifiers or erbium-doped fiber laser. 2) directly used for laser processing: 808 am high-power semiconductor lasers provide several kilowatts of output power and hundreds of quasi-continuous watts of continuous output power, reliable working life of thousands of hours.
