摘　　要：降低SBS相位共轭腔的启动阈值以及如何提高输出光束的质量一直是人们关心的课题。报道了在YAG激光器上运行一种新型对撞增强型YAG受激布里渊散射相位共轭激光腔的输出特性。该腔具有较低的启动阈值和较高的输出能量;该腔型最高能输出150mJ的能量,输出脉宽最窄为11ns,光束发散角为1.3mrad,输出能量和光束质量都很优良。How to decrease the threshold and how to prove the quality of output beam of phase conjugation cavity is a problem. A colliding-enhanced cavity is reported. It has higher output energy and narrower pulse widths. The output energy of the cavity will reach 150 mJ, the pulse width of it will reach 11 ns, the divergence angle is about 1.1 mrad. The quality of reformative cavity is improved. The results of pulse widths and output energies are given.
