最优数棱镜组及棱镜耦合扩束支腔计算

Calculation of Optimal Prism Numbers and the Loss of Prism-coupled Beam-expanding Branch Cavities

本文给出扩束棱镜组的最优数计算和取定公式,可使其单程透过率取得接近最大值的较大值。给出使棱镜耦合扩束支腔的单程损耗基本一致的简便计算方法,可省去繁琐的数值求解运算。

The eaculation and determination of optimal numbers for beam-expanding prism group are given to make the single-pass transmittivity close to the theoretical maximum. The simple calculation method given can cause the single-pass loss of prism-coupled beam-expanding branch cavities to be basically the same as that by the numerical operation, eliminating the tedious work.
