摘要: 激光晶体吸收激光二极管的泵浦光能量,产生激光振荡的同时有相当一部分泵浦光能量会转变为激光晶体的热量并耗散在晶体内,产生的热效应严重影响到激光器的性能和品质。通过对于激光晶体端面泵浦方式的分析,利用半解析热分析方法得出了晶体内部温度场和热形变场的计算方法,并对几种典型的掺Nd3+离子晶体的温度场和端面热形变场及其产生差异的原因进行了定量分析。研究方法和得出结果可以应用到内有热源、具有轴对称形式的模型中,对于激光二极管泵浦的全固态激光器的设计提供基础理论的铺垫。

Abstract: In diode pumped all-solid-state laser system laser crystal absorbing diode pumped energy will generate laser oscillation,simultaneously quite a part of pump energy will be translated into heat which is dissipated inside crystal.The thermal phenomena induced thermal effects seriously influence laser's performance and quality.According to laser crystal end-pumping mode analysis,laser crystal's interior temperature field and thermal distortion field calculation means are obtained by semi-analytical thermal analysis method.Under the same working conditions several typical Nd-ion doped laser crystal's temperature field and end face thermal distortion field as well as reasons of discrepancy are quantitatively analyzed.The analysis method and research results can also be applied to analyze temperature field and thermal distortion field of inner thermal source with axis-symmetrical profile models.The work will supply theory groundwork for design of diode pumped all-solid-state lasers. -
