摘　　要：通过实验测量了工作电流对半导体激光器发射波长的影响;采用光线追踪法模拟计算出泵浦光在Nd:YAG棒内的分布情况,采用直接泵浦方式,设计了高效率的半导体侧面泵浦Nd:YAG固体激光模块,最大输出功率为218W,最大光-光效率达37%,电光效率约为18.5%。The shift coefficient of the central wavelength of diode laser under different operating current was measured. The gain distrubution in the Nd：YAG rod was theoretically studied using ray tracing program. Without the help of collimating lens, a high efficiency diode- side- pumped module was designed with maximam output power of 218W. The maximum optical -optical efficiency is 37% and the electrical -optical efficiency is about 18.5%.
