Abstract
This study aims to investigate the behavior of pulsed Laguerre higher-order cosh-Gaussian (LHChG) beam as they travel through turbulent oceanic environments. The propagation of the pulsed LHChG beam is analyzed using the extended Huygens-Fresnel principle and the Fourier Transform method. Additionally, the effects of ocean turbulence, transverse position, and initial beam parameters on the spectral intensity of the beam are examined numerically. The relative spectral shift of the pulsed LHChG beam in oceanic turbulence as a function of the transverse coordinate is also analyzed through numerical simulations and depicted graphically. Our results show that the spectral intensity of the beam depends on oceanic parameters such as the rate of dissipation of kinetic energy per unit mass of fluid, the dissipation rate of temperature variance, the ratio of temperature and salinity contributions to the refractive index spectrum and pulse duration. This research provides a physical explanation of the spectral transition of the pulsed LHChG beam propagating through the turbulent ocean. The findings of this study have potential applications in information coding and transmission.
