Title (EN) METHOD AND SYSTEM FOR EXTENDING OPTICS LIFETIME IN LASER PROCESSING APPARATUS
(FR) PROCÉDÉ ET SYSTÈME PERMETTANT DE PROLONGER LA DURÉE DE VIE D'UNE OPTIQUE DANS UN APPAREIL DE TRAITEMENT AU LASER
Abstract:
(EN) Methods and apparatus for extending the lifetime of optical components are disclosed. A beam of laser energy directed along a beam path that intersects a scan lens, through which it can be transmitted. The beam path can be deflected within a scan region of the scan lens to process a workpiece with the laser energy transmitted by the scan lens. The scan region can be shifted to a different location within the scan lens, e.g., to delay or avoid accumulation of laser-induced damage within the scan lens, while processing a workpiece.
(FR) La présente invention concerne des procédés et un appareil permettant de prolonger la durée de vie de composants optiques. Un faisceau d'énergie laser est dirigé le long d'un trajet de faisceau qui coupe une lentille de balayage, à travers lequel il peut être transmis. Le trajet de faisceau peut être dévié à l'intérieur d'une région de balayage de la lentille de balayage pour traiter une pièce à usiner avec l'énergie laser transmise par la lentille de balayage. La région de balayage peut être décalée vers un emplacement différent à l'intérieur de la lentille de balayage, par exemple pour retarder ou éviter l'accumulation de dommages induits par laser à l'intérieur de la lentille de balayage, tout en traitant une pièce à usiner.
