片状放大器泵浦腔屋脊形反射器性能分析

摘要: 用蒙特卡洛光线追迹法模拟和比较屋脊形截面反射器与平板反射器的光传输性能，分析反射器构型对泵浦腔性能的影响。三维光线追迹结果显示：在本文设定的腔体构型条件下，屋脊形反射器腔的光传输效率可达63％，优于平板反射器腔的传输效率(η≤56%)。

Abstract: The results of 3D raytracing analysis of roof and flat reflector profiles are presented in this paper. The Monte Carlo simulation show that the rooftype reflector gi ves a 63% geometrical transfer efficiency and the flat shapetype reflector gives a lower transferef ficiency (＜56%),while both reflector profiles have similar pumping uniformity ．
