Abstract

Arbitrary moments of elliptical Gaussian-Schell beams in turbulent atmosphere is studied. An analytical formula for arbitrary moments of elliptical Gaussian-Schell beams in turbulent atmosphere is derived. As an example, the kurtosis parameter for elliptical Gaussian-Schell beams in turbulent atmosphere is investigated in detail. The comparison between the variations of the kurtosis parameter for elliptical Gaussian-Schell beams with different parameters is made. Meanwhile, the difference between the kurtosis parameter in vacuum and in turbulent atmosphere is analyzed and discussed.
