摘　　要：激光器光学系统的热效应会影响激光的传输和激光器的使用,为了研究热效应对半导体激光器光学系统的影响,利用ANSYS有限元软件对多单管激光器单元模块进行了热应力分析.模拟分析了光学器件对应输出功率的热特性,并通过Matlab软件利用Zernike多项式进一步拟合分析了输出功率对应系统光学器件的光学特性.结果表明:光学元件在热效应的影响下像差主要为像散,为后续像差补偿方式的设计提供指导.The thermal effect of a laser optical system will affect the transmission of the light and the use of laser. To study the influence of thermal effect of the laser optical system, the finite element analysis software of ANSYS was used to build a thermal-stress analysis about single emitter laser unit module system in this paper. The thermal characteristics of the device corresponding for different output powers were studied,and the optical properties of optical device was analyzed by the software of Matlab using Zernike polynomial further. Results show that the main aberration of optical element under the influence of thermal is astigmatism,which provides a guidance for design of aberration compensation mode later.
