We introduce a higher-order complex source that generates elegant Laguerre-Gaussian waves with radial mode number n and angular mode number m. We derive the integral and differential representations for the elegant Laguerre-Gaussian wave that in the appropriate limit yields the corresponding elegant Laguerre-Gaussian beam. From the spectral representation of the elegant Lauguerre-Gaussian wave we determine the first three orders of nonparaxial corrections for the corresponding paraxial elegant Laguerre-Gaussian beam.
我们引入了一种高阶复源,它能产生具有径向模式数n和角向模式数m的优美拉盖尔 - 高斯波。我们推导了优美拉盖尔 - 高斯波的积分和微分表示,在适当的极限下,该表示会产生相应的优美拉盖尔 - 高斯光束。从优美拉盖尔 - 高斯波的频谱表示中,我们确定了相应傍轴优美拉盖尔 - 高斯光束的前三阶非傍轴修正。
