摘　　要：本文用光束偏转法和干涉法分别测量了以熔石英为窗口材料的铜蒸气激光器及其窗口的热透镜效应。实验表明：铜蒸气激光器工作时的等效热透镜由放电管内气体负透镜和窗口的正透镜复合而成，理论分析与实验结果相符。The thermal lenses in operating copper vapor lasers and in the fused silicawindows were measured by using of the deflection method and the interferometer methodrespectively.Experimental results show that the overall thermal Jens is composed of anegative lens in the discharge gas and two postive lenses in two pieces of laser windows.Theoretical analysis agrees well with experimental results.
