摘　　要：从理论上导出了起始腔的稳定性与腔内光学元件的布置及其参数之间的关系 ,实验验证了高衍射损耗的非稳定起始腔有利于提高相位共轭激光器的调 Q效果 ;实验观察了蒸馏水作为 SBS介质时 ,相位共轭激光器的输出特性 ,并与高增益的二硫化碳介质作了相应的比较 ,分析了它们之间差别的产生原因。In this paper, the influence of the primary resonator′s stability on the Q switch is experimentally studied, the results have shown that unstable primary resonator with high diffraction losses can improve the Q switch effect of phase conjugation cavity laser. The characteristic of output pulses from two types of phase conjugation cavity lasers with H 2O and CS 2 SBS medium, was compared and analyzed.
