Propagation of partially coherent flat-topped vortex beams through non-Kolmogorov atmospheric turbulence

摘要

The spreading of partially coherent flat-topped vortex beams in non-Kolmogorov atmospheric turbulence and the evolution of the average intensity and coherence vortices are studied based on the extended Huygens-Fresnel principle and the non-Kolmogorov model introduced by Toselli et al. [Proc. SPIE 6551, 65510E (2007)], where the effect of non-Kolmogorov power spectrum on the beam propagation properties and the evolution behavior is stressed. The results are illustrated numerically and interpreted physically. A comparison with previous work is also made.
