摘要

An expression for a multi-Gaussian correlated anomalous vortex beam (MGCAVB) is presented based on coherence theory, and the intensity equations for this MGCAVB in an anisotropic turbulent ocean are derived. Based on the results from the numerical analysis, the intensity properties of an MGCAVB during propagation are discussed. A circular or elliptical flat shape can be attained for an MGCAVB in free space by adjusting the beam parameters. The flatness of an MGCAVB is determined by the sum index of the multi-Gaussian Schell-model source F, and the shape of an MGCAVB with a small topological charge M quickly becomes flat. The intensity shape of an MGCAVB in an anisotropic turbulent ocean gradually loses its flatness. This method for intensity shape modulation can be extended for use with other beams.
