Based on the moments method, the analytical expressions for the beam propagation factor, the kurtosis parameter and the orbital angular momentum density distribution of a vortex cosh-Gaussian beam (vChGB) propagating in free space are derived. Accord

The propagation of General Model vortex Higher-order cosh-Gaussian beam (GMvHchGB) in a maritime atmospheric turbulence has been studied analytically by the extended Huygens-Fresnel principle. Based on the derived formulae, we performed numerical sim

The current study examines the diffraction of Humbert beam of type-II by a helical axicon based on the diffraction integral formula. The considered beam is a new donut beam family which generated by converting the Bessel-Gaussian beams passing throug
