Abstract
In the given work the integrated moments of random intensity of the coherent fundamental Bessel–Gaussian optical beams propagating in turbulent atmosphere are theoretically investigated. It was shown, that on short path in the region of weak optical wave fluctuations a variance of the displacements of the center of gravity of a coherent fundamental Bessel–Gaussian optical beam always more than the similar characteristic of a coherent fundamental Gaussian optical beam. Influence of the size of the radiating aperture on value of a variance of the random displacements of the center of gravity of a coherent fundamental Bessel–Gaussian optical beam is analyzed during propagation in turbulent atmosphere with a spectrum of fluctuations of dielectric permittivity of air of Kolmogorov type with finite value of the outer scale of atmospheric turbulence.
