DEVICE AND METHOD FOR WORKING GLASS ELEMENTS OR GLASS-CERAMIC ELEMENTS BY MEANS OF A LASER

摘要: The problem addressed by the invention is that of providing a device and method with which break initation lines can be scribed into an element to worked, as rapidly true specifications possible, means laser. To this end, (1) for laser-working glass or glass-ceramic (2) provided, comprising: - ultrashort pulse laser (10), focussing optical system (3) concentrate beam (7) (10) elongated focus, power being sufficient produce filamentous damaged regions (6) inside pulses focussed in glass-ceramic, comprising lens (4) arranged path (10). A movement (9) moved transversely direction (70) so position axis (40) changed relative (7). change shifts incident point (71) on guided along predefined forming initiation line (12) moving (4).
