Abstract

An interference polarizer for forming a radially-polarized zero-order vortex Bessel beam with the wavelength of 1530 nm has been developed. The polarizer contains 33 layers of SiO₂ / Nb₂O₅ evaporated on a glass substrate using the vacuum electron beam method. The measurement of polarizer characteristics showed the ratio of transmittance of radially- and azimuthally-polarized beams to be 80:1 – 90:1 with the angle of incidence equal to 24.5 – 25°. The transmittance of radially-polarized light was not less than 75%. A radially-polarized zero-order vortex Bessel beam of high optical quality was formed with the help of the developed polarizer and a diffractive axicon.
