  • Publication number: 20230141696
    Abstract: A method for separating a portion from a sheet glass element having a thickness of at least 2 millimeters along an intended separation line that divides the sheet glass element into the portion and a remaining main part is provided. The method includes producing filamentary damages comprising sub-micrometer hollow channels in a volume of the glass sheet element adjacently aligned along the separation line; and heating and/or cooling the glass sheet element to cause expansion and/or contraction so that the portion detaches from the main part along the separation line. The portion and the remaining main part each remain intact as a whole. The step of producing the filamentary damages includes generating a plasma within the volume with laser pulses of an ultrashort pulse laser; and displacing points of incidence of the laser pulses over a surface of the glass sheet element along the separation line.

  • Patent number: 11618707
    Abstract: A method for separating a substrate of a brittle-hard material is provided. The method includes the steps of introducing defects into the substrate at a spacing from one another along a separation line using at least one pulsed laser beam; selecting an average spacing between neighboring defects and a number of laser pulses for generating a respective defect such that a breaking stress (?B) for separating the substrate along the separation line is smaller than a first reference stress (?R1) of the substrate and such that an edge strength ?K of the separation edge obtained after separation is greater than a second reference stress (?R2) of the substrate; and separating the substrate after introducing the defects by applying a stress along the separation line.

  • Patent number: 11534754
    Abstract: 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.

The edge regions extend in the longitudinal direction along the edge surface and along the side surfaces. The first edge region has elongated parallel filamentary damages that are parallel and adjacent to one another and, in particular, spaced apart equidistantly, in the longitudinal direction thereof extending transversely to the side surfaces and along the surface of the first edge region.

  • Publication number: 20220176494
    Abstract: A method of structuring a glass element having a first side face and a second side face is provided. The method includes the steps of: producing a filament-shaped flaw in the glass element with a pulsed laser beam along a focus line; etching to remove glass in the filament-shaped flaw to form a wall extending from the first side face towards the second side face, the wall having a boundary line that is tapered at a vertex between the wall and the first side face with a taper angle with respect to a perpendicular of the first side face; and adjusting the taper angle by controlling a feature of the focus line. The feature is selected from a group consisting of a position of the focus line, a length of the focus line, an intensity distribution of the focus line, and any combinations thereof.
