Fourier Method propagation for a Gaussian shape optical beam

涡旋光束在光束的传播方向上有一个位相项e，而且它拥有一个光束轨道角动量，该matlab程序实现了从一个高斯基模变换到涡旋光束的基本功能。(The vortex beam has a phase term E in the direction of beam propagation, and it has a beam orbit angular momentum. The matlab program realizes the basic function of transforming fro
