Generation of radially polarized beams based on the refractive optical elements with interference polarizing coatings

The calculation and simulation of an interference polarizer to generate radially polarized light are conducted. The method is based on the conversion of a conical wavefront as it passes through the interference polarizer. A multilayer optical coating can be applied on the surface of the axicon. It is shown that in this way we noticeably reduce both the operating angle of incidence and achieve a practically significant polarization degree of the generated beam at much lower energy losses.
