Beam wander of partially coherent twisted elliptical vortex beam in turbulence.

Based on the generalized Huygens–Fresnel theorem, the characteristics of beam wander in partially coherent elliptical vortex beams in anisotropic non-Kolmogorov turbulence are studied. Considering not only the vortex phase but also the twisted phase modulation in the partially coherent beams, the study of twisted phase modulation is carried out based on the content of the partially coherent elliptical vortex beam in order to research the relationship between the beam wander and the twisted phase modulation factor. It is found that twisted phase modulation and coherent modulation have a saturation region, and outside the saturation region, the twisted phase modulation can restrain the beam wander effectively.
