  • Publication number: 20210340050
    Abstract: A method includes: providing a plate-like glass element having side faces and an ultrashort pulse laser having a laser beam; directing the laser beam onto one of the side faces; concentrating the laser beam by focusing optics to form an elongated focus in the glass element; producing a filament-shaped flaw in a volume of the glass element by a radiated-in energy of the laser beam, a longitudinal direction of which runs transverse to one of the side faces, and the ultrashort pulse laser radiates in a pulse or a pulse packet having at least two successive laser pulses to produce the filament-shaped flaw; widening the filament-shaped flaw to form a channel by exposing the glass element to an etching including an etching medium which removes glass at a rate of less than 8 ?m per hour; and introducing rounded, hemispherical depressions in a wall of the channel by the etching.

  • Patent number: 11161766
    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: 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.

    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.
