Abstract

The exact full-wave generalization of the cylindrically symmetric scalar real-argument Laguerre–Gauss beam is determined. The radiation intensity of the resulting Laguerre–Gauss wave is deduced, and the main characteristics of the radiation intensity pattern are described. The total power $P_n$ is evaluated, where n is the radial mode number. By the use of $1∕P_n$ as the quality parameter, the characteristics of the quality of the paraxial beam approximation to the full Laguerre–Gauss wave are discussed.
