摘　　要：报道了在YAG激光器上运行一种改进对撞增强型YAG受激布里渊散射(SBS)相位共轭激光腔(改进型对撞腔)的输出特性。与未改进型撞腔相比,改进型对撞腔最高能输出150mJ的能量,输出脉宽最窄为11ns,光束发散角为1.1mrad;同等条件下,改进型对撞腔输出能量约提高了约40%,脉冲压窄了约10ns,发散角减小0.1mrad。An improved colliding-enhanced resonator cavity was proposed. The output energy of the improved cavity will reach 150 mJ, the pulse width will reach 11 ns, and the divergence angle is about 1.1 mrad. Comparing to original cavity, the output energy increases by about 40 percent, the width of output pulse decreases by about 10 ns, the divergence angle decrease 0.1 mrad under the same conditions.
