Paper Abstract

This work is devoted the research of coherent properties of the diffraction-free beams propagating in turbulent atmosphere. On the basis of the solution of the equation for the second-order mutual coherent function of a field the consideration of behavior of mean intensity and degree coherence of a cosine beam is developed. The mean intensity of a beam during propagation in turbulence decreases twice. The degree coherence of a beam at low levels of fluctuations has oscillatory character, and the number of fluctuations is defined by a value of a beam parameter. At high levels of fluctuations the degree coherence of a beam becomes closer to the similar characteristic of a plane wave.
