摘要: 采用菲涅耳棱体隔离器(FROI)作为铷玻璃激光双程放大器级间的耦合,本文报导了对双程放大FROI的隔离比及其随光束口径的变化情况,并分析了调整精度对隔离比的影响。Abstract: Using FROI as a coupler in Nd-glass round-trip amplifier,the isolationcoefficient of over 100 in a round-trip amplifier has been obtained. It is analysed the in-fluence of the limited beem-diameter and incident beem direction to the isolation coeffi-clent .
