摘　　要：报道了LD端面泵浦的Nd∶YAG/LBO U形腔腔内倍频激光器,通过对连续LD泵浦源脉冲调制选取合适的占空比,大幅降低了晶体的热透镜效应。在泵浦功率8.05 W,重复频率1 kHz条件下,获得了输出功率1.38 W、脉宽8 ns、峰值功率172 kW、光束质量M2因子1.3的绿激光输出,光-光转换率达17%。The U shape cavity is used in end pumped Nd：YAG/LBO SHG configuration is reported. The thermal effect was reduced greatly by modulating the LD and using suitable duty cycle,when the incident power is 8.05 W, repetition rate is 1 kHz, 1.38 W TEM00 mode green laser with pulse width 8 ns is obtained by optimization of the system. The optical to optical conversion is 17% and the peak power is up to 172 kW. M^2 coefficient is 1.3.
