Title
(EN) DEVICE FOR THE LASER PROCESSING OF MATERIALS
(FR) DISPOSITIF POUR L'USINAGE LASER DE MATERIAUX
Abstract
(EN)
The present invention can be used in the fields of welding, soldering and cutting as well as in other types of thermal processing using light and laser beams. This invention essentially relates to a device for the laser processing of materials, wherein said device comprises a laser radiation source as well as a preliminary heating source. The preliminary heating source consists of an ellipsoidal reflector having electrodes and a light guide arranged in its radiating focus. The device also includes a focalisation system. One end of the light guide is connected to the laser radiation source, while the other end is connected to the optical focalisation system. The reflector includes an insert having an inlet opening formed therein for letting the laser beam through. The optical focalisation system is arranged in the opening of the annular insert so that the optical axis of the light guide may coincide with the optical axis of the optical focalisation system extending between the electrodes. The insert can also be provided with an ellipsoidal or paraboloidal reflecting surface. The optical focalisation system can also be mounted at the end of the reflector beyond the aperture angle.

Cette invention peut être utilisée dans des processus de soudage et de découpe, ainsi que dans d'autres types d'usinage thermique où l'on utilise des faisceaux lumineux et laser. Cette invention concerne essentiellement un dispositif destiné à l'usinage laser de matériaux, lequel dispositif comprend une source de rayonnement laser ainsi qu'une source de chauffage préliminaire. Cette dernière se compose d'un réflecteur ellipsoïde dans le foyer rayonnant duquel sont montés des électrodes et un guide optique. Le dispositif comprend également un système de focalisation. Une extrémité du guide optique est connectée à la source de rayonnement laser, tandis que l'autre extrémité est connectée au système optique de focalisation. Le réflecteur comprend un insert comportant un orifice d'entrée qui va laisser passer le faisceau laser. Le système optique de focalisation est disposé dans l'ouverture de l'insert annulaire de sorte que l'axe optique du guide optique puisse coïncider à l'axe optique du système de focalisation qui passe entre les électrodes. L'insert peut avoir une surface réfléchissante ellipsoïde ou paraboloïde. Le système optique de focalisation peut également être disposé au niveau de l'extrémité du réflecteur au-delà de l'angle d'ouverture.
