摘要: 为了研究LD面阵侧面泵浦Nd：YAG晶体吸收光场的均匀性，本文提出了一种新的求解泵浦光路径的计算方法。首先建立了适用于不同泵浦结构的激光二极管多侧面泵浦全固态激光器的晶体吸收光场分布模型；然后模拟并分析了单向面阵泵浦结构各参量：bar条个数、bar条间隔、bar面倾斜程度对面阵泵浦晶体吸收光场均匀性及泵浦效率的影响。本文研究为LD侧面泵浦全固态激光器的设计和研究提供理论基础。Abstract: To study the uniformity of the absorption light field of the side-pumped Nd:YAG crystal in the LD planar arrays, a new calculation method for solving the pump optical path is proposed in this paper. Firstly, we establish a distribution model of crystal absorption light field suitable for laser diode multi-side-pumped all-solid-state laser with different pump structures; Then, the influence of the parameters of unidirectional planar array pump structure, including number of bars, the interval of bars, inclination of bars surface, on the uniformity and pumping efficiency of absorption light field in planar array pumped crystals are simulated and analyzed. This study provides a theoretical basis for the design and research of LD side-pumped all-solid-state laser.
