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.
