摘　　要：建立了半导体侧面泵浦固体激光介质内泵浦光能吸收分布情况的数值模型。模拟计算了不同泵浦参数下棒状介质和板条介质内泵浦光能的吸收分布，计算结果和有关实验结果符合得很好。得出了半导体侧面泵浦机构中介质尺寸、介质吸收系数和半导体激光器发光面到介质泵浦面距离这三个参数对泵浦均匀性的影响。The calculating model of pumping energy distribution in a solid laser medium side pumped by semiconductor laser diode is made in this paper.The absorption and distribution of the pumping energy is analog calculated and the result of the calculation agrees with the result of some experiment very much.After analyze the result of the calculation we get the general rule that how the parameters(size of the medium,absorption coefficient of the medium and distance between the laser diode and the medium)affect the homogeneity of pumping energy distribution in the medium.The advantage and disadvantage of the rod medium and slab medium side pumped by laser diode are analyzed too.
