Abstract

L'invention concerne un dispositif de gravure au laser permettant de traiter la surface et l'intérieur d'un verre. Le dispositif comprend un plateau, un laser CO2, un laser YAG, un laser indicateur He-Ne, un télescope à faisceau divergent et un miroir qui sont disposés sur une plate-forme supérieure du plateau. Un dispositif de focalisation de laser CO2 et un dispositif de focalisation de laser YAG sont suspendus à la plate-forme supérieure. Une table de travail opérationnelle à deux dimensions est installée sous le dispositif de focalisation de laser. Un dispositif de refroidissement par eau, un bloc de puissance laser et un ordinateur sont disposés au voisinage du plateau. Le laser CO2 est focalisé sur une surface de verre de façon à la faire craquer et à réaliser une gravure plate. Le groupe de lentilles de focalisation du dispositif de focalisation de laser YAG est déplacé de haut en bas, de façon à ce que le point endommagé à l'intérieur du verre forme un stéréogramme. On peut ainsi graver l'intérieur du verre.
