摘要
引用光流体模型[2]的光束径向能量的不变积分分别讨论了光束波面畸变和振幅分布不均匀对光束质量因子M2的影响;引入了光束质量因子的两种新定义,并讨论了这两个新质量因子与M2的关系。
Abstract
In this paper, by using the hydrodynamical model of optics and the invariant integral of the radial component E⊥ of the beam cross-section energy, we analyze the influences on the beam quality M2 factor from the wave surface distortion and from the nonuniform amplitude distribution respectively, introduce two new kinds of definitions of the beam quality, and discuss the relation among these two definitions and the M2 factor.
