Abstract

Evolution of polarized umbilics in a laser beam propagating in an optical system consisting of two anisotropic crystals with crossed optical axes and a Faraday cell is analyzed. It is shown that the phase perturbation caused by the second crystal results in radial shifts of the singularities, whereas the rotation of the plane of polarization when the Faraday cell is placed between the crystals causes angular displacements. When the Faraday cell is placed behind the second crystal, it provides additional fine control of the linear and angular shifts of the optical vortices.
