Propagation behavior of a new generalized laser beam through marine environment

Abstract

Abstract Based on the extended Huygens-Fresnel principal, we investigate the propagation behavior of Generalized Hermite cosh-Gaussian (GHCG) beam through new random medium namely maritime atmospheric turbulence. The analytical formula of the GHCG beam propagating in the considered turbulent medium is derived. The impacts of the maritime turbulence parameters and the source beam parameters on the propagation characteristics of the GHCG beam are analyzed using numerical calculations. The results show that the evolution process of average intensity for a GHCG beam through maritime turbulence will gradually lose its properties and its resistance to fluctuations and then evolve faster into Gaussian distribution in the far field as the turbulent constant structure increases and as the inner scale size of the turbulence decreases. The obtained results can be significantly contributed to the practical application for free-space optical communication and remote sensing.
