Abstract

High power lasers for industrial use, mainly for materials processing, having an annular laser cavity and means (16) for generating an axi-symmetric laser beam which is polarized. The conical mirrors can be axicons (20) or waxicons (18) with a selective coating method for producing a laser beam with preferred azimuthal and preferred radial polarization based on the use of conical intra-cavity mirrors or their equivalents.
