Noncoherent Bessel-Gaussian beam during propagating in turbulent atmosphere

In the given work the results of theoretical researches of prominent features of formation of a Bessel-Gaussian beam of noncoherent optical radiation in a uniform medium and a turbulent atmosphere are presented. The problem analysis is based on the analytical solution of the equation for the transverse second-order mutual coherence function of a field of optical radiation. The behavior of the coherence degree, the phase of the complex coherence degree, the coherence radius and the integral scales of the coherence degree and the squared coherence degree of a noncoherent Bessel-Gaussian optical beam depending on beam parameters are studied: from the radius of the Gaussian factor of a field of a beam and from the component of the wave-vector, which is orthogonal to the direction of propagation of optical radiation.
