Abstract

We have experimentally analyzed the behavior of Gaussian beam with elliptical cross-section passed through the uniaxial crystal in direction near perpendicular to the crystal’s optical axis. The projection of total angular momentum flux on the axis consists of projection of two components: the spin (SAM) and orbital (OAM) angular momentum. We have revealed that in anisotropic media the SAM describes the polarization state of the beam cross-section and OAM reflects the shape and topological charge of the singularity at ordinary and extraordinary beams. The sum of projections SAM and OAM remains constant. The oscillations of spin-orbital angular momentum projection were described experimentally during the crystal was rotated around z axis with small beam inclination. The low changes in the extraordinary beam cross section and their correlation with polarization state allow us to analyze the form of angular momentum conversion and possibility for generation of polarizing singularities. The feasibility of optical vortex generation in the system of uniaxial crystal with tilted Gaussian beam was theoretically and experimentally investigated.
