报道了微型铒玻璃激光器的阶段性研究成果，研究了在自由振荡情况下输出膜片反射率、氙灯气压以及激光电容的大小对激光输出的影响。采用电光调Ｑ，获得了８ｍＪ的巨脉冲输出；采用转镜调Ｑ，获得了１２ｍＪ的巨脉冲输出，脉宽８０ｎｓ。 This paper reports the results of the phased research on the erbium-doped glass laser and the influence of the output film reflectance, the pressure of the xenon lamp and the size of the laser capacitor on the laser output under free oscillation. The use of electro-optic Q-switched, access to a giant pulse output 8mJ; using mirror Q, obtained 12mJ giant pulse output, pulse width 80ns.
