In this study, the closed-form of the propagation of the kurtosis parameter of non-truncated Hollow higher-order Cosh-Gaussian beam passing through an ABCD optical system was derived based on the second-order and fourth-order irradiance moments. Numerical examples were provided to illustrate the analytical results. The kurtosis parameter of specific cases such as fundamental Gaussian, Cosh-Gaussian, and higher Cosh-Gaussian beams can also be deduced from the main formula of this study. The obtained results are consistent with previous works and offer a more comprehensive investigation of the kurtosis parameter of laser beams.

The obtained results were consistent with the previous works and constitute a more generalized investigation of kurtosis parameter of laser beams.
