Abstract: A plate-like glass element includes a pair of opposite side faces and an opening having a transverse dimension of at least 200 μm. The opening is delimited by an edge. The edge has a plurality of rounded, substantially hemispherical depressions that adjoin one another. The plurality of rounded, substantially hemispherical depressions having abutting concave roundings which form ridges.

Abstract: A composite includes a component and a glass or glass ceramic material. The component has a first coefficient of expansion α1 and the glass or the glass ceramic material has a second coefficient of expansion α2. The glass or the glass ceramic material has a surface with a thickness and thickness differences (TTV) within the surface, and thickness fluctuations (LTV). The composite has a residual stress in the glass or the glass ceramic material (WARP), and a geometric and material-physical degree of compatibility KG≥4.

Abstract: A plate-like glass element including a pair of opposite side faces and at least one channel introduced into the glass of the glass element. The at least one channel joins the side faces and opens into the side faces. The at least one channel has a rounded wall and a transverse dimension of less than 100 μm. The at least one channel extends in a longitudinal direction that runs transverse to the side faces. The rounded wall of the at least one channel has a plurality of rounded, substantially hemispherical depressions.

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 μm per hour; and introducing rounded, hemispherical depressions in a wall of the channel by the etching.
