摘　　要：在对储能网络的快速恒流充电和氙灯的预燃状态下,通过控制火花隙触发开关上的电压和重复频率,实现“热容”模式下运行的氙灯泵浦钕玻璃激光器的激光输出。初步实验指标达到重复频率4Hz,40J/脉冲,出光25s,输出能量4kJ,工作间隙10min,每次工作出光可将1.5cm厚的铝板打穿。该激光器的功率输出可定标放大到kW量级以上,适合进行一些固体热容激光器特点的相关实验。Under the conditions of the quick-charging to energy storage net with constant current and the pre-igniting of the Xe lamp, by controlling the voltage value and the repetitive frequency of the spark switch, the laser output in the heat capacity mode using a Nd:Glass laser pumped by the Xe lamp was obtained. Its output parameters were as follows: the repetition frequency was 4 Hz, the single-pulse energy 40 J, the lasting time 25 s, the output energy 4 kJ, and the operating interval 10 min. In addition, when the lasing on target each time, the laser could penetrate an aluminum plate with thickness of 1.5 cm. The output power of the laser could be scaled up to the order of kW, therefore many experiments related with the heat capacity mode can be made completely.
