摘　　要：本文采用表面热透镜技术对10.6μmCO2激光辐照下的样品微弱吸收进行了研究,并对实验结果进行了分析。对10.6μm激光辐照下光学薄膜样品中的温度场进行了数值模拟,应用夏克—哈特曼波前传感器对几种不同的基底材料和光学薄膜在10.6μm激光辐照下的热畸变进行了测量。In this paper, the weak absorption of different optical thin films irradiated by 10.6μm CO2 laser has been measured by using the surface thermal lensing technology.The experimental results have been analyzed and discussed.The temperature fields of the thin fdms irradiated by 10.6μm CO2 laser have been simulated and analyzed. By using the Shack - Hartmann wavefront sensor, the thermal distortion of the different substrates and thin frlms irradiated by CO2 laser were studied experimentally.
