Effects of turbulence on the transmission of partially coherent vortex beams in the ocean environment

摘要

The analytical expressions of mode probability density (MPD) and crosstalk probability density (CPD) for Laguerre-Gaussian correlated Schell-mode (LGCSM) beams propagating through oceanic turbulence are established based on the geometrical optics approximation. Using the derived formulae and numerical simulation, the propagation characteristics of a single LGCSM beam in turbulent ocean are quantificationally analyzed in detail. The numerical results for the effects of all kinds of parameters on the MPD and CPD curves of a LGCSM beam propagating in the ocean environment are presented and illustrated. This research is expected to provide a convenient way and useful guidance to describe and treat the propagation of laser beam in turbulent medium.
