摘　　要：对加反射镜测量放大自发辐射方法测量小信号增益系数的物理模型作了修正。给出了修正后小信号增益系数的计算公式。测量了横向脉冲放电Ｓ２气体激光介质的小信号增益系数，最大值为０．０８２ｃｍ－１。并对计算结果作了分析和讨论。The modification of the physical model for the calculation of small signal gain by measuring spontaneous emission magnified with a mirror is done. The analytical expressions of small signal gain from the model modified are given. The coefficients of the small signal gain of a S 2 laser medium pumped by transverse fast discharge are obtained, and the maximum of g 0 is 0.082 cm -1 . And the results are analyzed and discussed.
