  • Publication number: 20200407263
    Abstract: A method for the production of glass or glass ceramic elements from flat glass or glass ceramic parts is provided where the edges of the glass or glass ceramic elements are treated by a combination of two processes. The flat glass or glass ceramic element with an edge surface connecting the two side surfaces is produced. The edge surface has at least one first elongated, strip-shaped edge region and at least one second elongated strip-shaped edge region, which are formed by a ground edge. 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: 20200376603
    Abstract: A method for preparing a workpiece for separation is provided that includes providing a workpiece that is transparent for light of a pulsed laser beam, splitting the laser beam into two partial beams using an optical system, directing both partial beams onto the workpiece, and moving the workpiece and the partial beams relative to one another. The partial beams are directed onto the workpiece incident at different angles to the normal of the irradiated surface and superimposed inside the workpiece such that the partial beams interfere with one another to form a sequence of intensity maxima inside the workpiece. The intensity at the intensity maxima is sufficiently high to modify the material of the workpiece so that a chain-like periodic pattern of material modifications is formed along a path defining a separation line.

  • Publication number: 20200369551
    Abstract: A method for processing glass elements is provided. The method includes introducing a perforation line for parting a glass element introduced into the glass element during or after a hot processing process at an elevated temperature of at least 100° C. Spaced-apart filamentary flaws are introduced into the glass element along the predetermined course of the perforation line by a pulsed laser beam of an ultrashort pulse laser, and, during or after the introduction of the filamentary flaws, the glass element is cooled down so as to produce a temperature gradient, which induces a mechanical stress at the filamentary flaws, whereby the breaking force required for parting the glass element along the perforation line is reduced.

  • Publication number: 20200290152
    Abstract: A method provides for producing modifications in or on a transparent workpiece using a laser processing device. The laser processing device has a short pulse or ultrashort pulse laser that emits laser radiation having a wavelength in the transparency range of the workpiece and which has a beam-shaping optical unit for beam shaping for focusing the laser radiation. The transparent workpiece is composed of a material that has a plurality of phases, of which at least two phases have different dielectric constants, of which in turn the one phase is a phase embedded in the form of particles, which phase is substantially surrounded by the other phase, and wherein the product of the volume of the particles specified in cubic nanometers and the ratio of the absolute value of the difference of the two different dielectric constants to the dielectric constant of the surrounding phase is greater than 500.

  • Publication number: 20200199007
    Abstract: A method is provided that includes producing filamentary damages in a volume of a glass or glass ceramic element adjacently aligned along a separation line and 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.

  • Publication number: 20190329251
    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.

  • Publication number: 20190329252
    Abstract: A method for the production of microfluidic cells using a disc-shaped glass element is provided. The disc-shaped glass element has a thickness of at most 700 micrometers is structured in such a way that it has at least one opening. The opening connects the two opposite-lying, parallel side faces of the glass element. The side faces are attached to a glass part so that the opening is sealed by the two glass parts to form a microfluidic cell having a cavity enclosed therein. The cavity is suitable for the conveyance of fluids. The attachment of the glass element to at least one of the two glass parts is produced by an adhesive that is applied onto the side face of the glass element. During application of the adhesive, the at least one opening in the glass element is left free of adhesive.

  • Patent number: 10407336
    Abstract: A method for cutting a thin glass including the steps of guiding, by a transport device, the thin glass ribbon over a levitation support, and directing, within a range of the levitation support, a laser beam onto the thin glass ribbon, which heats up the thin glass ribbon at an impingement point of the laser beam. The method also includes the step of blowing, by a cooling jet generator, a cooling fluid onto the track heated by the laser beam so that a region heated by the laser beam is cooled down and a mechanical stress is created. The cooling fluid contains vapor of a liquid at a saturation ratio of at least 0.5 or a plurality of liquid droplets. The liquid droplets form a contact angle on a surface of the thin glass ribbon which is smaller than that of water on the same surface.
