报道了采用激光二极管端面抽运a轴切割的Nd:YVO4晶体自拉曼和频激光的实验研究。从谐振腔结构、晶体膜系以及和频晶体的选择方面对激光系统进行了设计，对连续运转和声光调Q下和频激光器的性能进行了研究。以KTP晶体为和频晶体，在12 W的抽运功率下，获得了580 mW的558.6 nm连续黄绿激光输出，光光转化效率为5%。在17.5 W的抽运功率和30 kHz的声光调Q重复频率下，获得了最高平均功率为1.71 W、脉冲宽度为21 ns的黄绿激光输出，光光转化效率为9.8%。

Sum-frequency mixing of a laser diode end-pumped a-cut Nd:YVO4 self-Raman laser is reported. Reasonable designing of cavity construction and crystal coating, as well as choosing of sum-frequency mixing crystal are considered. The laser system is optimized for continuous-wave mode and Q-switched mode operation. Continuous-wave yellow-green laser with output power of 580 mW and wavelength of 558.6 nm is achieved at a pump power of 12 W, and the corresponding optical-optical conversion efficiency is about 5%. With pump power of 17.5 W and Q-switch repetition frequency of 30 kHz, yellow-green laser output power up to 1.71 W is achieved whose pulse width is 21 ns and optical-optical conversion efficiency is 9.8%.
