摘　　要：　使用等价腔概念,对高功率固体多棒激光腔的动态特性作了分析,推导出了多棒等价g参数和等价腔长的一般公式,由此可得出多棒腔等价g参数图上的动态工作特性曲线和临界光焦度,以数值算例说明多棒腔的动态工作特性。讨论了用适当调整腔镜和棒间距来补偿光焦度偏离的方法,并得出了相应的解析公式。所得结果可作为高功率固体腔设计的参考。Using the concept of equivalent resonators, dynamical characteristics of highpower solidstate multirod laser resonators are analyzed. The general expressions for equivalent gparameters and equivalent resonator length of multirod resonators are derived which permit us to obtain the dynamical characteristic curve and critical refractive powers on the equivalent gparameter diagram for multirod resonators and to illustrate their dynamical characteristics with numerical examples. In addition, the method of compensating a discrepance of the refractive power by a suitable adjustment of the distances between the mirror and the rod is discussed and the related analytical formula is given.
