用于连续高功率YAG激光器的高斯镜稳定腔的设计

Gaussian stable resonators design for high power CW YAG laser

本文通过对高斯镜热透镜稳定腔（ＧＲＭＳＲ）内光束特征的分析，提出了设计该类激光谐振腔的一般原则，并设计了平平腔型高斯镜稳定腔。实验结果与理论分析相符，并得到高输出功率、高光束质量的连续ＹＡＧ激光输出。

Based on the analyzing of beam transmission characteristics inside Gaus-sian reflective mirrors stable resonator(GRMSR)with thermal lensing,the general principles for design of the kind of resonators and plane parallel resonators are presented in this paper.The experimental results are well accordent to theoretical analysis.And the high power,high beam quality CW YAG laser beam is abtained.
