摘要
建立了片状激光介质的热－弹性－光三维模型,利用ANSYS软件分析了片状激光介质在热容模式下,不同工作条件下的温度场和应力场分布,并计算出在抽运不均匀条件下应力场对光束质量的影响,进行了相应的实验验证,结果表明热容模式下的热致双折射效应是影响光束输出特性的主要因素。实验结果与理论模拟基本吻合。
Abstract
A three-dimensional thermo-elasto-optical distortion model for the laser disk has been constructed, the temperature and stress distributions under different work conditions on a laser disk of a heat capacity laser have been simulated by using ANSYS software, and the effect of the stress on the beam quality with nonuniform pump has been analyzed. An demonstration experiment is done, and the results are accordant to the simulation results. The results show that at the heat capacity mode, the thermal induced birefringence is the main reason to affect the output beam properties.
