Abstract
In order to study propagation properties of J0-correlated partially coherent flat-topped beams in atmospheric turbulence,the average intensity distribution were derived based on extended Huygens-Fresnel principle,and the analytical expression of beams waist width was obtained with the second-order moment method.Then,the effects of propagation distance,correlation lengths of source,structure constant and orders of flat-topped beams on average intensity distribution and beam width were analyzed.It was show that higher order flat-topped beam was less affected by atmospheric turbulence and it was less broadened.Results also show that maximum central intensity value can be obtained by adjusting the correlation lengths of source.
