The criterion for optimizing the high-power acousto-optically ${Q}$-switched self-Raman yellow laser is originally explored for the repetition rate within 100–500 kHz. The minimum allowed value for the gate-open time is experimentally verified to be determined by the pulse buildup time. By using the minimum allowed gate-open time, the highest conversion efficiency can be achieved to raise the output power by approximately 20% in comparison with the conventional results. At a repetition rate of 200 kHz, the maximum output power at 588 nm can be up to 8.8 W at an incident pump power of 26 W. Furthermore, a practical formula is developed to accurately calculate the threshold pump power as a function of the gate-open time for a given repetition rate.

优化重复频率高达500 kHz的高功率声光Q开关自拉曼黄光激光器的标准

最初针对100-500 kHz内的重复率探索了优化高功率声光$ {Q} $开关自拉曼黄光激光器的标准。闸门打开时间的最小允许值经过实验验证，由脉冲建立时间确定。与传统的结果相比，通过使用最小的允许的栅极打开时间，可以实现最高的转换效率，以将输出功率提高大约20％。以200 kHz的重复频率，当入射泵浦功率为26 W时，在588 nm处的最大输出功率可以高达8.8W。此外，开发了一个实用公式来精确计算作为门限函数的阈值泵浦功率-给定重复率的开放时间。
