Abstract

Based on the intensity moments formalism, the closed-form expressions of the kurtosis factor of some truncated and non-truncated laser beams with rectangular symmetry, as Hermite-cosh-Gaussian and super-Gaussian beams, are derived and illustrated numerically. Some particular cases are also deduced. Our results are consistent with previous works and constitute a more generalized study of kurtosis factor of laser beams.

Keywords : Kurtosis factor; Super-Gaussian; Hermite-cosh-Gaussian; Cosh-Gaussian; Hermite-Gaussian; Hard-edged aperture.
