利用普克尔盒在二极管泵浦碱金属激光器（DPAL）中演示了腔倒空现象。我们从3.1W的连续波铯DPAL产生了峰值功率为77W的14ns半高宽脉冲。由于高压电源的限制，脉冲重复频率被限制为100 Hz。观察到脉冲的时间分布中包含的周期性尖峰，推测是由于两个纵模之间的干扰。结果，脉冲的峰值功率从存储在光学谐振器中的平均功率增强。据我们所知，这是第一次演示增强脉冲输出产生的DPAL。
Cavity dumping is demonstrated in a diode-pumped alkali laser (DPAL) using a Pockels cell. We generated a 14 ns FWHM pulse with a peak power of 77 W from a 3.1 W continuous wave cesium DPAL. Due to the limitation of the high-voltage power supply, the pulse repetition rate is restricted to 100 Hz. Periodic spikes contained in the temporal profile of the pulse were observed, presumably due to interference between the two longitudinal modes. As a result, the peak power of the pulse was enhanced from the average power stored in the optical resonator. To the best of our knowledge, this is the first demonstration of enhanced pulsed output generation in a DPAL.
