我们设计了一种脉冲重复频率范围为5- 20khz的高平均功率二极管侧泵浦Nd:YAG声光调q激光器。采用双同步调q开关增加保持电流，在10 kHz和110 ns脉冲持续时间下获得200 W以上的平均输出功率，调q效率达到80%以上，光效率达到20%，激光器的不稳定性为1%。实验研究了不同谐振腔结构对激光器保持电流的影响。
We have designed a high-average-power diode-side-pumped Nd:YAG laser acousto-optically Q-switched at a pulse repetition rate range of 5-20 kHz. Double synchronized Q-switches were used for increasing the hold-off current and obtained more than 200 W average output power at 10 kHz and 110 ns pulse duration with more than 80% Q-switching efficiency and 20% optical-optical efficiency and instability of laser was 1%. The effects of various configurations of resonator on hold-off current of the laser have been experimentally studied.
