用光束传播法（Ｂｅａｍ Ｐｒｏｐａｇａｔｉｎｇ Ｍｅｔｈｏｄ）计算并分析了用半导体激光器端面抽运的１．０８４ μｍ ＮｄｖＴｉｖＬｉＮｂＯ３ 波导激光器输出功率的理论模型。用Ｎｄ３＋ 的原子复极化率来描述受激辐射光的增益与抽运光的吸收，且考虑到前进与后退光波的相互作用，给出激活媒质的粒子数空间反转分布，并修改了抽运吸收和受激辐射截面的取值，使之适用于半导体激光器从波导激光器端面抽运，计算值与实验值符合得很好。
The theoretical model of the output power of a 1.084 μm NdvTivLiNbO3 waveguide laser pumped by the end face of a semiconductor laser was calculated and analyzed by the Beam Propagating Method. The repolarization ratio of Nd3 + is used to describe the gain of the stimulated emission and the absorption of the pump light. Considering the interaction between the forward and backward light waves, the spatial inversion of the particle number of the activation medium is given and the pumping The values of the absorption and stimulated emission cross sections are suitable for the pumping of the semiconductor laser from the waveguide laser end face. The calculated values are in good agreement with the experimental values.
