Comparative studies of characteristics of Bessel and “perfect” vortex beams with a topological charge 9, created using a binary silicon axicon and a “holographic” diamond axicon with continuous profile at a wavelength of 141 μm, are carried out. Beams with linear and radial polarization are investigated. An example of the use of a perfect radially polarized beam for the excitation of vortex plasmon-polaritons on a cylindrical conductor is given.
