Abstract

New polarization converter for transforming the circulary polarized laser modes into cylindrical vector beams (CVB) including beams of higher orders is proposed. The generation of CVB in birefringent crystals is studied analytically and experimentally in paraxial and non-paraxial regimes. At sharp focusing (in the non-paraxial case) two focuses corresponding ordinary and extraordinary beams are formed along the crystal’s axis. The results are extended to the generation of higher-order radially and azimuthally polarized mode beams. Using the simulation the possibility of fabricating crystal-based devices suitable for application in fiber optics was shown. The results of the experimental study on the generation of cylindrical vector beams in a crystal of Iceland spar agree with the results of the simulation.
