Effects of oceanic turbulence on a multi-cosine-Lorentz correlated beam

Abstract

The model of a special beam array called multi-cosine-Lorentz correlated (MCLC) beam is introduced, and the coherence function of a MCLC source is related to the multi-cosine function and Lorentz function. The expressions of a MCLC beam in anisotropic oceanic turbulence are derived. Based on the obtained equations, the intensity shapes of a MCLC beam with small δ will become a beam array composed of Lorentz beamlets quickly. The beamlets of a MCLC beam in anisotropic oceanic turbulence can overlap and the shape of a MCLC beam can become a spot pattern, and the speed of overlap phenomenon can be accelerated on the stronger oceanic turbulence. The array pattern of a MCLC beam can be modulated by adjusting source parameters and oceanic turbulence. The results show a new method to provide a beam array composed of Lorentz beamlets.
