圆柱形激光共振腔的耦合能量

Coupling Energy of Columniform Laser Resonant Cavity

分析了圆柱形波导气体激光器中的耦合损耗,给出了最低阶波导模EH11的耦合损耗与反射镜位置、曲率半径的函数关系.研究表明:反射镜的位置和半径存在着最佳值,在取得最佳值时,可得到最低的耦合损耗.

This paper analyses the coupling wastage in columniform wave guide gas laser, and gives the function between the coupling wastage of laser guide modulo EHll and the position and radius of reflector. The study shows that the lowest coupling wastage can be obtained with the best position and radius of the reflector.
