摘　　要：在给出大功率激光器输出耦合镜基模和多模两种理论模型的基础上分析了材料吸收对激光器输出光束的影响。对于在通常使用参数下，ＧａＡｓ和ＺｎＳｅ 材料输出耦合镜吸收对于激光束的影响及热透镜效应作了数值分析。This article gives two theoretical model of fundamental and multi-mode for high power CO 2 laser,and based on the two mode,analyzes the material absorption of the output coupling mirror for its influence on the laser output beam.Numerical analyses of GaAs and ZnSe output coupling mirrors for the influence on the laser beam and the effect of thermo lens are carried out.

关 键 词：输出耦合镜 材料吸收 热透镜效应 激光器 激光束
