高重复率紧凑型微脉冲全固态激光器

本文设计并实现了一台高重复率，紧凑型微脉冲全固态激光器。YAG晶体， Nd:YAG晶体和Cr4+:YAG晶体键合为一个单块晶体作为谐振腔。优化计算了Cr4+:YAG晶体的初始透过率，耦合输出透射率和泵浦光斑大小。对激光器的性能进行了测试，结果表明该激光器适合于空间激光测距。

A high repetition rate, compact micro-pulse all-solid-state laser is designed. The diffusion bonded crystal of YAG, Nd:YAG, and Cr4+:YAG is taken as a monolithic cavity. The optimized initial transmission, output coupling, and pumping size of Cr4+:YAG are calculated. The experimental results show that the laser satisfies the requirement of a spaceborne laser range finder.
