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 highpower solidstate multirod laser resonators are analyzed. The general expressions for equivalent gparameters 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 gparameter 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.
