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.
