摘要：
We have studied the spatial dynamics of spin-to-orbital angular momentum conversion for zero-order and higherorder circularly polarized Bessel light beams, propagating along the optic axes of uniaxial and biaxial crystals. We have established that interaction of the Bessel beam with a uniaxial crystal slab makes possible practically complete conversion of the optical spin [angular] momentum to [orbital] angular [momentum]. In a biaxial crystal slab, during such a conversion the angular momentum is partially transferred to the medium, and as a result the slab undergoes rotation.
