Paper Abstract

This article is devoted to studying of statistical characteristics of intensity fluctuations of the fundamental BesselGaussian optical beams propagating in turbulent atmosphere. Research of intensity fluctuations is developed by a method of the statistical moments, particularly, the behavior of the fourth-order coherence function of the optical radiation field is analyzed. The asymptotic solution for area of weak fluctuations of intensity is derived, using it calculations of a variance and spatial correlation function of intensity fluctuations of a fundamental Bessel-Gaussian optical beam in turbulent atmosphere are realized. The effect of relative easing of intensity fluctuations of a fundamental BesselGaussian optical beam in comparison with the similar characteristic of a Gaussian optical beam is discovered. It is shown that intensity fluctuations of a fundamental Bessel-Gaussian optical beam are essentially non-uniform in cross-section of an optical beam. Spatial correlation function of intensity fluctuations of a fundamental Bessel-Gaussian optical beam within its first maximum is weakly sensitive to change of parameter of a Bessel optical beam.
