像散椭球高斯光束的理论分析与实验模拟
The Theoretical Analysis and Experimental Simulation of Astigmatic Elliptic Gaussian Beam
摘要
从理论上讨论了具有简单像散特性的椭圆高斯光束的处理方法, 在实验中利用两个正交的柱透镜模拟球面双轴透镜对半导体激光器的输出光束进行变换, 得到较为理想的结果, 即把椭圆高斯光束处理为近似圆高斯光束。
Abstract
A method for dealing with a kind of elliptical Gaussian beam which has simple astigmatic character is discussed, and two across cylindrical lens are used to imitate a spherical biaxial lens on transforming the beam from a semiconductor laser. A fairly perfect result is obtained that elliptical Gaussian beam is transformed into an approximately similar circular Gaussian beam.
