Average Intensity of Partially Coherent Lorentz Beams in Oceanic Turbulence

Abstract

Partially coherent Lorentz beams have been introduced to describe the output of the diode laser, which have been investigated due to the special spreading properties. The analytical expressions of partially coherent Lorentz beam propagating in oceanic turbulence are derived. Using the derived equations, the average intensity distributions of partially coherent Lorentz beam are analyzed and discussed. It is shown that the partially coherent Lorentz beam with smaller coherence length will evolve into the Gaussian-like beam faster, and the beam propagation in oceanic turbulence will spread faster with increasing strength of oceanic turbulence. The results have potential application in underwater optical communications and sensing.
