摘　　要：报道了一种基于主振荡—功率放大(MOPA)方式工作的脉冲激光器。为了获得高重复频率、高平均功率的激光输出,采用尺寸为4 mm×35 mm×160 mm,掺杂浓度为1%的Nd∶YAG薄板条。通过对侧面出光的浸入式板条激光器进行LD阵列侧面泵浦,在泵浦光平均功率为15 k W时,实现了稳定的4.15 k W的激光输出,谐振腔的光光转换效率为27.7%。在此基础上,采用两个放大模块建立了一级振荡二级放大的MOPA装置,输出光平均功率达6.4 k W。A pulsed laser based on master-oscillator power amplifier（ MOPA） is reported. In order to get laser output of high repetition frequency and high average power,the Nd ∶ YAG thin slab was used,whose size is 4 mm × 35 mm × 160 mm and the Nd3 ＋doping concentration is 1%. Through side-pumped LD array for the immersion slab laser,stable laser output power of 4. 15 k W is obtained when the average power of pump light is 15 k W,and the optical-optical conversion efficiency of resonant cavity is 27%. On the basis of that,two amplifiers were adopted to establish MOPA,the average output power of laser reaches 6. 4k W.
