Influences of oceanic turbulence on Lorentz Gaussian beam

Based on the extended Huygens-Fresnel integral, the propagation of a Lorentz Gaussian beam in oceanic turbulence is investigated. The influences of oceanic turbulence parameters (the rate of dissipation of turbulent kinetic energy per unit mass of fluid, the rate of dissipation of mean square temperature, and the relative strength of temperature and salinity fluctuations) on average intensity of a Lorentz Gaussian beam are analyzed by using the numerical examples. The results show that a Lorentz Gaussian beam propagating in stronger oceanic turbulence will spread faster. (C) 2017 Elsevier GmbH. All rights reserved.
