摘　　要：为了满足小型光电系统对微小型大功率激光器的研制要求,通过液态金属传热设计,提高散热效率,使得激光器在小体积下实现高能量输出。采用复合板条工作物质集成谐振腔以及激光放大技术,在激光电源电流80A、工作频率为5Hz时,激光器在1064nm输出单脉冲能量为160mJ,脉宽为6ns,发散角为3mrad的激光。In order to fulfill the requirements of small opto-electronic systems for miniature high power lasers,a heat conduction manner based on liquid metal was designed,which improved the heat transfer efficiency,and a high energy laser with a small volume was made.Using compound slab active materials integrated resonator and laser amplification technology,when the supply current was 80 A and the pulse frequency was 5 Hz,a 160 mJ pulse laser at 1 064 nm was obtained,with a pulse width of 6 ns and a divergence angle of 3 mrad.
