Publication number: 20240116797Abstract: A method includes producing filamentary damages in a volume of a glass or glass ceramic element that are adjacently aligned along a separation line and that extend obliquely relative to a surface of the glass or glass ceramic element, and separating a portion from the glass or glass ceramic element along the separation line. The step of producing the filamentary damages includes directing laser pulses of an ultrashort pulse laser obliquely on the surface so that the laser pulses have a light propagation direction that extends obliquely relative to the surface and so that the filamentary damages resulting from the laser pulses have the longitudinal extension that extends obliquely relative to the surface, generating a plasma within the volume with the laser pulses, and displacing the laser pulses at points of incidence over the surface along the separation line.Type: ApplicationFiled: December 15, 2023Publication date: April 11, 2024Applicant: SCHOTT AGInventors: Andreas ORTNER, Albrecht SEIDL, Frank-Thomas LENTES, Fabian WAGNER

Patent number: 11534754Abstract: A method for producing a cavity in a substrate composed of hard brittle material is provided. A laser beam of an ultrashort pulse laser is directed a side surface of the substrate and is concentrated by a focusing optical unit to form an elongated focus in the substrate. Incident energy of the laser beam produces a filament-shaped flaw in a volume of the substrate. The filament-shaped flaw extends into the volume to a predetermined depth and does not pass through the substrate. To produce the filament-shaped flaw, the ultrashort pulse laser radiates in a pulse or a pulse packet having at least two successive laser pulses. After at least two filament-shaped flaws are introduced, the substrate is exposed to an etching medium which removes material of the substrate and widens the at least two filament-shaped flaws to form filaments. At least two filaments are connected to form a cavity.Type: GrantFiled: April 26, 2019Date of Patent: December 27, 2022Assignee: Schott AGInventors: Andreas Ortner, Andreas Roters, Hauke Esemann, Markus Heiss-Chouquet, Fabian Wagner, Laura Brueckbauer, Stephanie Mangold, Vanessa Hiller
