模拟仿真具有轨道角动量的LG模式的涡旋光，并且给出了它的相位分布图。-The vortex light of the LG mode with orbital angular momentum is simulated and its phase distribution is given.

生成叉型图，产生轨道角动量光束，可画单个或多个，有无强度调制的叉型图，欢迎下载(The cross graph is generated to generate the orbital angular momentum beam)

matlab仿真轨道角动量，模态值从0到+3，画出平面波和涡旋波的示意图(Matlab simulation orbital angular momentum, modal value from 0 to + 3, draw the plane wave and vortex wave diagram)
