Abstract

The exact full-wave generalization of the azimuthally varying scalar real-argument Laguerre-Gauss beam is obtained. The radiation intensity of the resulting azimuthally varying real-argument Laguerre-Gauss wave is determined. The main characteristics of the radiation intensity pattern are discussed. The total power P(n,m) is determined, where n is the radial mode number and m is the azimuthal mode number. By the use of 1/P(n,m), the characteristics of the quality of the paraxial beam approximation to the real-argument Laguerre-Gauss wave are investigated.

摘要

得到了方位角变化的标量实宗量拉盖尔 - 高斯光束的精确全波推广形式。确定了由此产生的方位角变化的实宗量拉盖尔 - 高斯波的辐射强度。讨论了辐射强度分布的主要特征。确定了总功率P(n,m)，其中n是径向模式数，m是方位角模式数。通过使用1/P(n,m)，研究了傍轴光束对实宗量拉盖尔 - 高斯波近似的质量特性。
