摘要
本文从高斯光束出发对半导体激光器的既简单又经济实用的准直法-单透镜准直法进行了理论分析和实验。实验结果与理论计算基本相符,表明只要采用一个相对孔径D/f较大的透镜,并置其对半导体激光器有合适位置,则可以得到令人满意的准直效果。
in this paper, a simple, economical and pratical collimation method -single lens collimation method of semiconductor lasers is calculated theoretically and experimented on from Gaussian beam. The calculation is in accordance with the results of enperlment.Thus it show that when using a lens whose relative aperture (D/f)is bigger and choosing a suitable realative position between the lens and the semiconductor laser we can get the quite satisfactive collrmation effect.
