用高亮度激光二极管作抽运源, 研究了连续、 腔内倍频和被动调Q Nd:GdVO₄激光器的输出特性。 在抽运功率为881 mW时获得了119 mV的连续绿光输出, 光-光转换效率13.5%。 用Cr⁴⁺:YAG作可饱和吸收体实现了Nd:GdVO₄激光器的被动调Q运转, 脉冲宽度为116～24 ns, 重复频率在500 kHz～1.8 MHz范围内可调。

Characteristics of a high-brightness laser-diode end-pumped CW and passively Q-switched Nd:GdVO₄ laser ware studied. Using KTP as the intracavity frequency doubler, 119 mW green output power was obtained at a pump power of 881 mW, corresponding to a optical-to-optical efficiency of 13.5%. Passively Q-switched operation was realized using Cr⁴⁺:YAG as the saturable absorber. Stable pulses with pulse duration of 116～24 ns and repetition rate of 500 KHz～1.8 MHz were generated.
