摘　　要：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 designing construction of Nd：glass laser cavity was double flashlamp pumped, symmetrical,close coupling and unfocused.Through 10 s experiment,laser beam patterns were measured at 10 Hz repetition rate of double flashlamp in heat capacity operation and general water-cooling operation successively.The contrastive result shows that the output energy of single pulse and average output power of heat capacity operation is about 1.4 multiple than water-cooling operation.The result was favor of the different characteristic of Nd：glass laser in heat capacity operation.
