Abstract

The partially coherent Lorentz–Gauss vortex beam generated by a Schell-model source has been introduced. Based on the extended Huygens–Fresnel principle, the cross-spectral density function of a partially coherent Lorentz–Gauss vortex beam propagating in oceanic turbulence is derived. The influences of coherence length, topological charge M, and oceanic turbulence on the spreading properties and position of the coherence vortex for a partially coherent Lorentz–Gauss vortex beam are analyzed in detail. The results show that a partially coherent Lorentz–Gauss vortex beam propagating in stronger oceanic turbulence will evolve into a Gaussian-like beam more rapidly as the propagation distance increases, and the number of coherent vortices will change.
