Axial intensity of Bessel higher-order cosh-Gaussian beam propagating in a turbulent atmosphere

Résumé

Abstract In the present paper, the effects of the turbulent atmosphere on the propagation properties of Bessel higher-order cosh-Gaussian (BHChG) beam are investigated. Based on the Rytov approximation and the extended Huygens-Fresnel integral diffraction, analytical expression of the axial intensity for BHChG beam is evaluated and the results of some laser beams are deduced as particular cases from our research. Some graphical representations have been carried out to study the influence of the incident beam parameters and the atmospheric turbulence on the considered beam. The obtained results can be useful for atmospheric optics applications in free-space optical communications.
