摘　　要：将二极管泵浦单纵模Nd∶YAG激光器作为主振荡器,三级灯泵Nd∶YAG放大器及SBS相位共轭镜组成双通放大MOPA系统,经两个放大单元的行波放大,实现能量达6.58J,脉宽3.6ns,束散角1.7mrad,重复频率10Hz激光输出,峰值功率达1.82GW。A doublepass configuration of MOPA system is realized by a diode pumped,single longitudinal mode Nd∶YAG master oscillator and three flashlamppumped YAG amplifiers with a phase conjugating stimulatedbrillouinscattering cell.After single-pass amplifiering of two amplifier cells,the laser output energy of 6.58J,pulse duration of 3.6ns,divergency angle of 1.7mrad and 10Hz repetition rate,the peak power is 1.82GW.
