采用MOPA结构的高功率双端面泵浦Nd：YVO（4）激光器实现了重复频率高达500 kHz的稳定调Q。实验中使用的是热键合Nd：YVO（4）晶体。在重复频率为500 kHz的声光调Q工作中，振荡器产生的平均功率为35 W，光-光效率为41.7%。108 W的平均功率获得了主振荡器功率放大器（MOPA）配置，包括两个放大器级，对应于总的光-光效率为42.2%。脉冲宽度为48 ns，脉冲峰值稳定度<2.5%。光束质量优于2倍衍射极限（M（x）（2）= 1.99，M（y）（2）= 1.76）。
A high power, dual-end-pumped Nd:YVO(4) laser with a MOPA configuration was stably Q-switched at repetition rate up to 500 kHz. The thermally bonded Nd:YVO(4) crystal was used in our experiment. In acousto-optically Q-switching operation at repetition rate of 500 kHz, 35 W average power was produced by the oscillator, with optical-optical efficiency of 41.7%. 108 W average power was obtained by a master oscillator power amplifier (MOPA) configuration including two amplifier stages, corresponding to the total optical-optical efficiency of 42.2%. The pulse duration was 48 ns, with a stability of pulse peak value < 2.5%. The beam quality was better than two-times diffraction-limit (M(x)(2) = 1.99, M(y)(2) = 1.76).
