钕玻璃激光器采用双灯对称紧耦合非聚焦泵浦腔,先后以热容及常规水冷方式运行10s(重复频率10Hz),分别记录100个光脉冲的脉冲能量。通过对比实验分析脉冲能量变化趋势,热容方式运行的钕玻璃激光器的平均输出功率及单脉冲能量均高于常规运行方式,约为1.4倍。结合理论计算,验证了热容激光器在抽运阶段输出的全部脉冲串能量的理论值。该结果对进一步了解钕玻璃激光器热容运行方式的输出特性具有一定的参考价值。
The neodymium glass laser uses double-lamp symmetrical and tightly coupled non-focusing pump cavity, and successively runs heatsink and conventional water-cooling mode for 10s (repetition frequency 10Hz) to record the pulse energy of 100 light pulses respectively. Through the comparative experiment analysis of the pulse energy change trend, the average output power and single pulse energy of the neodymium glass laser operating in the heat capacity mode are higher than the conventional operation mode, about 1.4 times. Combined with the theoretical calculation, the theoretical value of the total pulse energy output by the heat capacity laser during the pumping stage is verified. The result has a certain reference value for further understanding of the output characteristics of the neodymium glass laser heat capacity operation mode.
