Lü Su-Ye %A JI Xiao-Ling %A Lü Bai-Da %J 中国物理快报 %D 2007 %I %X Directionality of a class of partially coherent cosh-Gaussian beams propagating in atmospheric turbulence is studied. It is shown that two partially coherent cosh-Gaussian beams may generate the same angular spread, and there exist equivalent partially coherent cosh-Gaussian beams which may have the same directionality as a fully coherent Gaussian laser beam in free space and also in atmospheric turbulence. The theoretical results are interpreted physically and illustrated numerically. %K 42 %K 68 %K Ay %K 42 %K 68 %K Bz %K 92 %K 60 %K Ta
