Effects of turbulent atmosphere on the propagation properties of vortex Hermite-cosine-hyperbolic-Gaussian beams

The propagation properties of a vortex Hermite-cosh-Gaussian beam (vHChGB) in atmospheric turbulence are investigated based on the extended Huygens–Fresnel diffraction integral and Rytov method. analytical formula for average intensity vHChGB propagating turbulent atmosphere is derived detail. influence strength distribution under change parameters conditions illustrated numerically discussed. Results show that profile initial remains unchanged within small distance range, at certain central peak appears, finally evolves into Gaussian profile–like far-field. rising speed faster when larger or such as order, charge waist width smaller. With decentered parameter b, changes wavelength larger, whereas reverse behavior occurs b large. obtained results may be useful practical applications optical communications remote sensing.
