光泵碱金属蒸气激光泵浦光源线宽压缩的分析

摘要

分析了各种压缩光泵碱金属蒸气激光泵浦光源线宽的方法,包括在Littrow结构中使用全息光栅、体布拉格光栅和F-P标准具.分析各种方法的实验装置,比较其取得的成果和优缺点,指出优化方向,为求寻找到一种装置简单,压缩效果显著,同时将功率损耗降到最小的方法提供了指导.%The approaches of compressing the line width of pump source of DPAL( diMe-pumped alkali vopor lasers) have been analyzed in this paper,including employment of holographic grating, volume Bragg grating and Fabry-Peret etalon in the Littrow structure. The setup of different ways have been analyzed and their results, advantages and disadvantages have been compared, providing scientific guidance to looking for a method which has a simple setup, efficient reduction of the line-width and the least power loss.
