Presently  for laser used as processing light source needs to amount to dozens of KW per cm2 of power density  how to increase power output and get smaller light spot for diode laser becomes a key problem. It is introduced that by designing beam shaping by ourselves and making use of optical system for beam blooming and focusing  808nm laser array composed of 20 bars eventually achieves the 1001.5w power output  coupling efficiency at 90%  11mm2 of light spot through experiments  which enables diode laser to be directly applied to cladding  welding and so on. 2012 IEEE.   Self-Q-Switched and Mode-Locked Cr,Nd:YAG Laser under Direct 885 nm Diode Laser Pumping 期刊论文  OAI收割 CHINESE PHYSICS LETTERS, 2012, 卷号: 29, 期号: 5 Jiang, M; Zhang, QL; Zhou, WJ; Zhang, J; Zhang, DX; Feng, BH 收藏  |  浏览/下载：21/0  |  提交时间：2013/09/24 AVERAGE OUTPUT POWER  ND-YAG  CR  EMISSION  LOCKING  GARNET  LEVEL  NDYAG LASER   Computer simulation of thermal focal length of laser crystal and thermally-near-unstable resonator 会议论文  OAI收割 2012 9th International Conference on Fuzzy Systems and Knowledge Discovery, FSKD 2012, Chongqing, China, MAY 29-31, 2012 作者:  Geng AC(耿爱丛);  Li BH;  Chen XB;  Yang XD;  Yang MJ(杨明江) 收藏  |  浏览/下载：18/0  |  提交时间：2013/02/26 Computer simulation  Fuzzy systems  Lasers  Gain medium  High beam quality  High order mode  High output power  Laser crystals  LD side-pumped  ND : YAG lasers  Output power  Pump power  SIMPLE method  Theoretical prediction  Thermal focal length
