Abstract:

The features of the transformation of linearly polarized Bessel light beams during their propagation through an electrically controlled liquid-crystal cell are studied theoretically and experimentally. Conditions were determined for realizing the spin–orbit transformation of Bessel light beams, which manifests itself through changes in polarization, phase, and spatial structure of the Bessel beam with the possibility of obtaining an azimuthally modulated light field intensity distribution.

Keywords:

Bessel light beams, spin-orbit transformation, liquid crystals
