摘要: 用布儒斯特角放置的多张放大器片作大口径电光开关的检偏器，不仅有利光束的传输，而且可以有效降低装置的工程造价和难度。本文计算了不同的片放张数、放大器增益和普克尔盒效率与系统隔离效率之间的关系。在多程系统上进行了实验测试，结果为在相同输入光强时，普克尔盒工作与不工作时输出光束强度相差8倍。

Abstract: It benefits to decrease the engineering cost and to debase the technical crisis that analysis polarizer composed of amplifier Nd3+:glass slabs located with the Brewster angle in large scale multi-passes laser facility. The relationships of the isolation efficiency with the numbers of slab, the growth of the amplifizer and the switch efficiency of Pockels cell are calculated theoretically. The experimental results indicated that the output energy of this isolation system is 1:8 as Pockels cell working on and off. -
