Propagation characteristics of non-uniformly Sinc-correlated blue-green laser beam through oceanic turbulence

The propagation model of non-uniformly Sinc-correlated blue-green laser beam in oceanic turbulence was developed according to generalized Huygens-Fresnel principles. Based on the cross-spectral density, intensity variations in different propagation distances were discussed. When the oceanic turbulence parameters were varied, intensity and lateral shifted intensity maximum were numerically simulated. The results show that the propagation distance and ocean turbulence parameters have a certain influence on the intensity self-focusing effect of the non-uniformly Sinc-correlated blue-green laser beam. When the propagation distance is certain, the effect of the rate of dissipation of mean-square temperature on the intensity self-focusing is greater than the rate of dissipation of kinetic energy and the relative strength of temperature and salinity fluctuations.
