利用二极管侧面泵浦的Nd：Gd0.6Y0.4VO4反跳放大器，实现了高功率被动调Q，脉冲宽度为18~32 ns。在泵浦功率为39W时，获得了~gt； 8W的平均输出功率。调Q输出的峰值功率可通过改变Nd的浓度在1.9-5.2kW范围内调节。与纯Nd：GdVO4相比，混合钒酸盐具有更高的调Q性能。
High power passive Q-switching was achieved with a pulse width of 18–32 ns by using a diode-side-pumped Nd:Gd0.6Y0.4VO4bounce amplifier. An average output power of > 8 W was obtained at a pump power of 39 W. The peak power of the Q-switched output was adjusted within 1.9–5.2 kW by changing the Nd concentration. The mixed vanadates showed significantly higher Q-switching performances in comparison with pure Nd:GdVO4.
