Compact and Efficient 600 mW Blue Laser with a Composite Nd:YAG
利用复合Nd: YAG实现600 mW高效紧凑型蓝光激光器

By using a composite Nd:YAG crystal, LBO intracavity doubling in a simple plane-curved cavity, efficient high power blue laser was realized. Through the thermo-lensing effect at LDA high power pumping, the optimum mode-match was attained. The output power at 473 nm was 600 mW with the absorbed pumped power of 15.09 W, and the efficiency was 3.98%.
