- Abstract
This study investigates the propagation of a pulsed Laguerre higher-order cosh-Gaussian beam in turbulent maritime environments. Using the extended Huygens-Fresnel principle and the Fourier Transform method, we derive the formula for beam propagation in a marine environment. The analysis includes the influence of maritime turbulence, transverse positions, and initial beam parameters on the spectral intensity of the propagated beam. Graphical representations illustrate these effects, and numerical calculations demonstrate the relative spectral shift at various radial coordinates. The findings reveal dependencies on the refractive index structure constant, pulse duration, and beam order. Notably, on-axis spectral intensity experiences a blue shift, while off-axis spectral intensity undergoes a red shift with increasing radial coordinate. The study also highlights specific cases of the considered beam, providing valuable insights for information coding and transmission applications.
