共焦非稳腔几何参数稳定性对输出光束的影响

Influences of Stability of Parameters of Unstable Confocal Resonator on Output Beam

分析了共焦非稳谐振腔几何参数Ｌ，Ｒ１，Ｒ２的微小变化对输出耦合系数和远场强度的影响，并结合本校研制的ＨＤＩ型激光器的具体结构，得出一些有意义的结论．

The influences of the disturbance of the parameters,such as L,R 1,R 2 ,on the output coupling and on the far field intensity of positive branch unstable confocal resonator are studied.The studies are applied to the HDJ I type laser of our university.Some significant results are obtained.
