摘要
本文根据椭圆高斯光束的传输特性,推导了椭圆高斯光束经光学系统后其远场发散角的表达式;分析了椭圆高斯光束的准直的特点;给出了使其准直效果最佳时光学系统的放置位置;并与圆高斯光束进行了比较。
In this paper, the expressions of the far-field divergence angles of the elliptical Gaussian beam through a optical system are deduced according to its propagation properties. The collimation characteristics of elliptical Gaussian beam are studied. The place of optical system where the collimating effect should be optimal is demonstrated. And a comparison between elliptical and circular Gaussian beam is made.
