ABSTRACT: An analytical formula for the average intensity of cosh-Gaussian (ChG) beams diffracted by an aperture in turbulent atmosphere
is derived and some limiting cases are discussed. By using the average intensity formula, some numerical simulation comparisons
are made and some special cases are studied, especially the influences of the ChG beam parameter (Ω0), the propagation distance, the aperture and its size on the average normalized intensity distribution. It is determined
that the evolution properties of the average normalized intensity profile in turbulent atmosphere with aperture are different
not only from those of free space with aperture but also from those in turbulent atmosphere without aperture.
