Beam Propagation through atmospheric turbulence for different degrees of global coherence

摘要

Fully coherent laser beams are very sensitive to the turbulence medium. Studies have shown that using partially coherent beams is an effective method to reduce this unsatisfactory feature. Unfortunately partially coherent beams are more expanded when they propagate thought turbulence medium. In this paper we have determined a special degree of global coherency, which optimizes beam propagation with respect to limiting factors (sensitivity to the turbulence and broadening).
