摘　　要：为了获得高能量532 nm激光输出,利用电光调Q晶体LN,通过调Q同步驱动技术和LD侧面泵浦板条技术,获得高能量窄脉宽1.06μm激光输出,泵浦非线性晶体KTP进行频率变换,实现高能量532 nm激光输出。在电源输入电流120 A、调Q驱动频率10 Hz的条件下,获得264 m J的1.06μm激光。利用该1.06μm激光泵浦KTP获得最高能量为185 m J的532 nm绿光激光输出,1.06μm到532 nm的转化效率为70%。实验结果表明:通过电光调Q技术和LD侧面泵浦技术,可以实现高能量窄脉宽1.06μm激光输出,泵浦KTP可获得高能量绿光激光输出。To get high energy green laser,using electro-optical Q-switched crystal LN,1. 06 μm high energy narrow width laser output is obtained through Q-switched synchronization driving technology and LD-side-pumped slab technology. KTP is pumped to get high energy green laser output. As the input current is 120 A and the Q-switched frequency is 10 Hz,1. 06 μm laser output energy is 264 m J,and optical-to-optical conversion efficiency is 70%. Experiment results indicate that high repetition narrow width 1. 06 μm laser can be obtained through electro-optical Q-switched driving technology and LD-side-pumped technology,and high energy green laser output can be gotten by pumping KTP.
