研究了用钛蓝宝石激光泵浦的Nd:YVO4固体激光器的特性。得到基频连续激光输出功率为190 mW,泵浦阈值为13 mW,光学斜效率为51%。用KTP晶体腔内倍频,得到二倍频激光输出功率为10 mW,总的光学转换效率为2.3%。给出了泵浦光波长(740～830 nm)与激光输出功率之间的关系。

The properties of Nd:YVO4 solid-state laser pumped with a Ti:sapphire laser have been investigated. The output power of 190 mW and the pump threshold of 13 mW have been obtained where the optical slope efficiency was 51%. The output power of 10 mW for the second-harmonic light was observed using an intracavity KTP crystal, and the total optical efficiency was 2.3%. The dependence of the output power on the pump wavelength ranging from 740 nm to 830 nm is given.
