摘要

We analyze the propagation characteristics of a General Model vortex Higher-order cosh-Gaussian beam (GMvHchGB) in a turbulent oceanic medium. The beam’s intensity expression is derived using the Huygens–Fresnel integral formula. Through numerical simulations, the average intensity distribution is evaluated, focusing on the effects of oceanic turbulence and the incident beam parameters. The results indicate that the received intensity depends on the initial parameters and the oceanic conditions. Notably, under stronger oceanic turbulence, the GMvHchGB a transformation, losing its initial structure and quickly evolving into a Gaussian profile. This transformation is influenced by a reduction in the dissipation rate of turbulent kinetic energy per unit mass or an increase in the dissipation rate of mean-square temperature and the ratio of temperature to salinity fluctuation. Additionally, the initial beam parameters significantly affect the GMvHchGB’s intensity in the oceanic turbulent medium. These findings offer insights into potential applications in underwater optical communication between ships, divers, and submarines, as well as imaging systems.
