Abstract
The theoretical study of the coherence distribution in the cross-section of a partially coherent vortex-free Bessel optical beam during propagation in a uniform medium has been performed. The paraxial approximation of the second-order transverse mutual coherence function of a partially coherent vortex-free Bessel optical beam obtained using the Huygens–Fresnel principle is analyzed. The dependence of the coherence degree of the partially coherent vortex-free Bessel optical beam on the parameters of the problem (in particular, on the transverse coherence length of the field of an optical source) is studied. It is found that if a partially coherent vortex-free Bessel optical beam has the property of axial symmetry, then the coherence degree of this beam at the optical axis has the same property. However, when the observation points are shifted from the optical axis of the partially coherent vortex-free Bessel optical beam, a dependence of the coherence of this beam appears both on the magnitude of the sum coordinate of the observation points and on the mutual orientation of the vectors of the sum and difference coordinates of the observation points.
