通过合理设计,精密调控各元件和温控电流,得到了平均功率为70mW,脉冲宽度为22ns,重复频率为14kHz,峰值功率高达230W的Nd3+∶GdVO4/Cr4+YAG绿光脉冲激光器·腔外采用望远镜系统聚焦,经KTP晶体倍频后,得到了平均功率为28.8mW,脉冲宽度为19ns,重复频率为14kHz,峰值功率高达108W的绿光激光输出,转换效率高达·指出了小光斑对倍频晶体带来的影响·

Based on reasonable designing, precise temperature controlling of the Cr^4＋ YAG, Nd ＋ GdVO4 and LD, passively Q-switched infrared laser was obtained with average output power of 70 mW, pulse duration of 22 ns, repetition rate of 14 kHz, and peak power of 230 W. Then by a piece of type-Ⅱ critical phase matching KTP crystal for extra-cavity and for the system of telescope second-harmonic generation, green laser at 532 nm was achieved with average power of 28. 8 mW, pulse duration of 19ns, and peak power of 108 W. The effect of small beam radium was also discussed.
