| Abstract: | Based on the extended Huygens-Fresnel principle and the first-order approximation of wave structure function, an analytical expression for the average intensity of flattened Gaussian beam (FGB) in non-Kolmogorov turbulence has been derived. The variations of normalized intensity with some parameters, such as wave coherence length, Fresnel number, waist width and the order of FGB are investigated in detail. |
