砷化镓（GaAs）具有良好的机械化学性能和透光性，因此常被用作高功率CO2激光器耦合窗。为了掌握高功率CO2激光器耦合窗热效应，以数理方法解析分析为基础，考虑混合模式振荡下GaAs耦合窗的温度场以及热形变分布情况。定量计算了GaAs耦合窗的温度场以及热形变情况。研究方法和所得结论具有普适性，可用于其他激光器腔内混合模式振荡状态下的热问题研究。

GaAs has the good mechanical and chemical properties and light transmittance ,so it is used as a coupling window of high power CO2 lasers .In order to solve the thermal effect problem of coupling win‐dow in high‐power CO2 lasers ,the paper ,based on the mathematical analytical method ,studies the blend‐ing‐mode oscillations of GaAs coupling window of the temperature field and thermal deformation distribu‐tion ,and then conducts the quantitative calculation of GaAs coupling window of the temperature field and thermal deformation .T he results show that :if the blending‐mode resonant pow er is 4000W in the CO2 la‐ser cavity ,maximum temperature rise of the GaAs window is 51 .4℃ ,and the max thermal distortion is 1 . 46μm .The research method and the finding ,for the universality ,can be applied to the research on other thermal effect under the blending‐mode oscillation state in laser cavity .
