摘　　要：本文报道了在YAG激光器上运行一种新型的对撞型受激布里渊散射环形相位共轭腔，与通常的直相位共轭腔比较，该腔输出能量和输出峰值功率的大小和稳定性都有很大的提高。实验给出了不同参数奈件下的输出能量以及峰值功率的大小和起伏情况。在泵浦电压为850-1000V时，峰值功率相对平均值时的相对起伏度在10％左右，输出能量的起伏度也不超过5％。线形腔同对撞腔相比，在相同的泵浦条件下，不论从输出能量和峰值功率的大小，还是从它们的稳定性，对撞型相位共轭腔明显地好于线形相位共轭腔。同时给出了理论模型，用MAPLE软件进行了模拟，结果与实验相一致。On this paper, a colliding-enhanced cavity was reported. It has low fluctuation of output energy and peak power compared with line phase-conjugate resonator. The results of output energy and peak power fluctuation under different conditions were given. The output energy and peak power fluctuation were 10 percent and 5 percent respectively as the pump voltage range from 850 to 1000. The output energy and peak power fluctuation are superior to linear phase resonator at the same condition, The theory model was given, and the simulation results used by MAPLE were accorded with the experimental results.
