Self-focusing of a partially coherent beam with circular coherence

Journal of the Optical Society of America A, 2017
In a recent publication [Opt. Lett.42, 1512 (2017)OPLEDP0146-959210.1364/OL.42.001512], a novel class of partially coherent sources with circular coherence was introduced. In this paper, we examine the propagation behavior of the spectral density and the spectral degree of spatial coherence of a beam generated by such a source in free space and in ...

Vortex array embedded in a partially coherent beam

Optics Letters, 2015
Method of generating a vortex array embedded in a partially coherent beam is proposed and experimentally demonstrated. The vortex array exists in the complex coherence function of a random field arising due to interference of three independent coherence functions with appropriate phase profiles.

Coherence vortices in partially coherent beams

Optics Communications, 2003
It is demonstrated that the spectral degree of coherence of a partially coherent beam may possess isolated pairs of points at which its phase is singular, and that in the neighborhood of these points the phase may possess a vortex structure. Partially coherent beams consisting of Hermite-Gaussian modes are considered as an example.
