Investigation of the formation of hybrid polarized laser beams using a four-sector polarization converter

Abstract

Abstract The paper presents the manufacturing technology of a four-sector polarization converter for the formation of beams with different hybrid polarizations. A calcite crystal was used as a transducer, two opposite sectors of which were etched to a depth of 1970 nm. The work is demonstrated and experimental patterns of the total intensity distribution, x-components and y-components in the wavelength range of 500-800 nm for the light transmitted through the transducer and also in the focus distribution are shown. The theoretical and experimental dependence of the degree of conversion is described depending on the parameters of manufacturing the sectors of a four-sector converter. For this purpose, a tunable laser was used in the experiment. The operation of the transducer for the vortex field was simulated.
