摘要: 通过对二极管角抽运板条固体激光器的稳态热效应分析,提出了在角抽运条件下激光介质内部热源分布的模型.以此为基础,从稳态热传导方程和边界条件出发,计算了激光介质中的温度分布;同时分析了这一特定温度分布条件下增益介质的应力分布以及由于温度分布和应力分布引起增益介质的光学畸变,这些结果可以为二极管角抽运全固态激光器的稳定设计提供基础理论依据.Abstract: The theoretical analysis of thermal effects in corner-bumped slab solid-state lasers is presented.A new model of the heat distribution is proposed.Based on this model,the distribution of temperature and stress is calculated.The optical distortion induced by the temperature and stress is also analyzed.These results may provide the fundamental theory for the stable design of corner-bumped all solid-state lasers.
