摘　　要：介绍了高功率激光放大器系统中磷酸盐激光玻璃的静态透过率测量。在正常运行条件下 ,4片长按布儒斯特角放置的国产N3 1钕玻璃片对 1.0 5 4um的激光波长平均静态透过率为 94 .5 % ,介质的损耗系数为0 .2 94 %cm-1,平均非激活吸收系数为 0 .14 6 %cm-1。在此基础上对片状放大器的增益系数的测量结果进行了修正 ,获得了 5 .2 5 %cm-1的小信号增益系数。In this paper,the static transmission of phosphate laser disk glass used in high power laser amplifier is measured. In normal research condition,the average static transmission at 1.054μm incident beam with four pieces of phosphate laser glass(N 31 ) disposed by Brewster angle is 94.5%,the loss coefficient is 0.294%cm -1 ,the average non-activity absorption coefficient is 0.146%cm -1 ,this N 31 glass is made in China. Based on them,the small signal gain coefficient value is amended and reached up to 5.25%cm -1 .
