【摘要】 为了获得更好的光束质量的输出，对二极管侧面泵浦激光器内增益分布均匀性进行研究；通过对工作物质内增益分布进行理论分析，利用仿真软件建立增益场模型，研究了LD单侧泵浦Nd:YAG激光器增益场模型；模拟中通过对不同泵浦功率下的LD单侧泵浦Nd:YAG激光器增益场与吸收光场均匀性进行对比，结果得到了不同泵浦功率下增益场分布均匀性与吸收光场均匀性分布并不一致，并不是简单直观等效为线性关系，为高低温环境下即开即用的LD侧面泵浦Nd:YAG固体激光器获得高光束质量、高效率的激光输出提供理论参考提供参考。更多还原

【Abstract】 In order to obtain better beam quality output, the gain distribution uniformity in diode side-pumped laser is studied.The gain field model of LD single-side pumped Nd:YAG laser is established by using simulation software through theoretical analysis of the gain distribution in the working substance.In the simulation, the uniformity of gain field and absorbed light field of LD single-side pumped Nd:YAG laser under different pumping power is compared.The result shows that the distribution uniformity of gain field and absorbed light field under different pumping power is not consistent, which is not a simple and intuitive equivalent linear relationship.Theoretical reference is provided for the high beam quality and high efficiency laser output of out-of-the-box LD side-pumped Nd:YAG solid-state laser in high and low temperature environment.更多还原
