根据高斯光束的特性，在matlab中作出束腰半径为0.5mm的高斯光束在束腰处的三维光强分布图。(According to the characteristics of the Gauss beam, the three-dimensional intensity distribution of the Gauss beam with the waist radius of 0.5mm at the waist is made in MATLAB.)

Matlab模拟多光束干涉光场分布，文件内包含计算所得的两束，三束，四束光干涉的光场分布。程序内可任意改变光束参数(this part of matlab code is used to stimulate the distribution of the strength of the multi-beam interference)
