An apparatus for laser machining for optically machining a workpiece. The apparatus comprises a plane polarized primary laser beam source (1) adapted to generate a primary plane polarized light beam (20); a beam splitter (2), adapted to split the primary light beam into a plurality of secondary light beams (22); a light modulator array (3), comprising an array of individually controllable elements (56) that are each adapted to be set to either allow each beam of the plurality of secondary light beams to traverse through, or effectively block it; a microlens array (5), comprising an array of microlens elements foci of predetermined lengths, said microlens array elements corresponding to the elements of the light modulator array so that light beam passing through an element of the light modulator array is focused by a corresponding element of the microlens array; and control means (9) adapted to independently switch each of the elements of the light modulator between a transparent and opaque modes in a predetermined manner.
L'invention concerne un appareil d'usinage laser optique de pièce, comprenant une première source laser à polarisation de plan (1) fournissant un premier faisceau à polarisation de plan (20); un diviseur de faisceau (2) divisant ledit faisceau en plusieurs faisceaux secondaires (22); un ensemble modulateur de lumière (3), à plusieurs éléments contrôlables individuellement (56) réglables pour la traversée de chaque faisceau secondaire ou pour le blocage de chaque faisceau secondaire; un ensemble microlentille (5) à plusieurs éléments de longueur focale prédéterminée, qui correspondent aux éléments de l'ensemble modulateur. Un faisceau traversant tel ou tel élément de l'ensemble modulateur est focalisé par un élément correspondant de l'ensemble microlentille; et un système de contrôle (9) assurant la commutation indépendante de chaque élément de l'ensemble modulateur entre des modes transparent et opaque, de façon préétablie.
