摘　　要：利用Fox-Li数值迭代法对方形镜和圆形镜形状的对称共焦腔的横向稳定场分布进行了仿真研究,给出迭代任意多次后的光场振幅分布和相位分布。另一方面,从理论上分析了方形镜和圆形镜对称共焦腔的横模场分布规律,并绘出光强分布的二维和三维图形。最后设计了简明的图形用户界面,能够选择腔镜类型、光腔参数等,使激光横模仿真更加简单直观,有利于对激光横模理论的深入理解。Using the Fox-Li numerical iterative method to simulate the stability lateral field distribution of a variety of shapes parallel plane cavity,and gives the iterative light field amplitude distribution and phase distribution after any number of times.The other hand,theoretical analysis was given to draw transverse mode distribution law of the confocal cavity with square mirror and circular mirror,and plot the intensity distribution of two-dimensional and three-dimensional graphics.Designed a simple graphical user interface,it is possible to select the type of resonator,the parameters of resonator etc,so that the simulation of laser transverse mode is more simple and intuitive,is conducive to the understanding of the theory of laser transverse mode.
