Abstract

We show both, experimentally and analytically, generation of bottle beam by uniaxial crystal, in the case optical axis of a uniaxial crystal tilted with respect to axis of a beam. Intensity and polarization structure of a bottle beam experiences dramatic changes. At the angle of 3.5 deg. closed three dimensional structure, of initially circularly polarized beam, breaks. Both analytically and experimentally, we demonstrate that if the beam initially linearly polarized, it structure changes faster than in the case of circular polarization and two focuses of bottle beam “switch” positions. We experimentally, generate arrays of tilted bottle beams with a uniaxial crystal.
