Abstract

The propagation of radially polarized partially coherent beams in uniaxial crystals orthogonal to the optical axis is investigated. The analytical formulae for the elements of the cross-spectral density matrix of radially polarized partially coherent beams propagating through uniaxial crystals orthogonal to the optical axis are derived. The effect of initial coherence and ratio of extraordinary and ordinary refractive indices on the intensity and effective beam widths is illustrated analytically and numerically. The results show that the propagation properties of radially polarized partially coherent beams in uniaxial crystals orthogonal to the optical axis are closely related to the initial coherence and the ratio of extraordinary and ordinary refractive indices.
