Abstract
(EN)
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.

Cette invention concerne des lasers de grande puissance, à usage industriel, et utilisés essentiellement dans le domaine du traitement des matériaux, lesquels lasers possèdent une cavité laser annulaire ainsi qu'un système (16) de génération de faisceau laser polarisé à symétrie d'axes. Les miroirs coniques peuvent être des miroirs coniques tronqués (20) ou des miroirs coniques tronqués en forme de W (18) qui possèdent un revêtement sélectif. Cette invention concerne également un procédé de production d'un faisceau laser ayant des polarisations azimutale et radiale préférées, à l'aide de miroirs coniques d'intracavité ou de leurs équivalents.
