“…On the other hand, turbulent atmosphere [30][31][32][33][34][35] causes the beam wander and intensity scintillation by inducing the intensity and phase fluctuation of beam, thus significantly impacting practical application. In addition, it is well known that we use power spectral models to describe atmospheric turbulence to date, and various power spectral models have been proposed, such as Kolmogorov spectrum, Tatarskii spectrum, von Karman spectrum, and non-Kolmogorov spectrum.…”

We obtained the analytical formulas of partially coherent electromagnetic elliptical vortex beam (PCEEVB) propagating through atmospheric turbulence with the help of the extended Huygens-Fresnel principle and explored the normalized average intensity distribution of PCEEVB in turbulence. It is worth noting that the PCEEVB appears new characteristics such as self-rotating, self-splitting, and self-healing in turbulence. It can be also found that the number of peaks caused by splitting of beams is relevant to the topological charge n. What’s more, reducing the ellipticity, magnifying the topological charge, and increasing the initial coherent length δ0 can improve the anti-turbulence ability of PCEEVB in turbulence. The multi-phase screen simulation results are consistent with the theoretical results. Our results will have significant implications for laser communications, laser radar, and laser remote sensing.
