Paper Abstract

The features of focusing of a Gaussian optical beam with any curvature of parabolic wave front a conic lens (an axicon) in a randomly inhomogeneous medium are studied. The analysis of a problem is based on the solution of the equation for the second-order mutual coherence function of a field of an optical beam. The distribution of mean intensity of an optical beam in longitudinal and transverse to direction of propagation of an optical radiation are calculated. The influence of a randomly inhomogeneous medium on a change of a radius of a central part of an optical beam in the range of a focal region for axicon is estimated. The stability criterion of a spatial structure generated thus a pseudo-Bessel beam to influence of random inhomogeneities of a medium is derived. The behavior of a coherence radius of the focused optical beam depending on characteristics of a randomly inhomogeneous medium is examined.
