Abstract

In the given work the theoretical research of characteristics of coherence of a Laguerre-Gaussian beam of noncoherent optical radiation in a uniform medium is carried out. The behavior of the mean intensity, the coherence degree, the phase of the complex coherence degree, the coherence radius, the integral scale of the coherence degree, and the integral scale of the squared coherence degree of the noncoherent Laguerre-Gaussian beams propagating in a uniform medium is particularly considered. In work it is shown that during propagation of a noncoherent Laguerre-Gaussian beam in a uniform medium the increase in any of mode numbers (both the radial, and angular mode numbers) leads to relative reduction of coherence level of the given beam in comparison with the Gaussian beam.
