[HTML][HTML] Polarization conversion under focusing of vortex laser beams along the axis of anisotropic crystals
SN Khonina, SV Karpeev, VD Paranin, AA Morozov - Physics Letters A, 2017 - Elsevier
We report the development of an optical system based on diffractive optical elements and
uniaxial crystals to produce radially and azimuthally polarized beams, including beams of
higher orders. The conditions for the generation of beams with different polarization states in
an anisotropic crystal with an arbitrary axially symmetric amplitude distribution are analyzed
theoretically. The results of the experimental study on the generation of cylindrical vector
beams in a calcite crystal agree with the results of the simulation.
