    Abstract: A glass article having a glass bump formed integrally thereon by laser-irradiation methods. The glass bump includes a lower region connected to an upper region by an inflection region. The lower region projects from a surface of the glass article and is defined by concavely rounded sides with a radius of curvature R1. The upper region includes a transition portion and a top portion. The transition portion is defined by convexly rounded sides with a radius of curvature R2. The transition portion connects to the lower portion via the inflection region. The upper portion connects to the transition portion and is defined by a convexly rounded top surface with a radius of curvature R3, which is greater than radius of curvature R2.

    Abstract: A method of forming a strengthened glass article is provided. The method includes providing a strengthened glass article. The strengthened glass article is in the form of a container including a sidewall having an exterior surface and an interior surface that encloses an interior volume. The sidewall has an exterior strengthened surface layer that includes the exterior surface, an interior strengthened surface layer that includes the interior surface and a central layer between the exterior strengthened surface layer and the interior strengthened surface layer that is under a tensile stress. A laser-induced intended line of separation is formed in the central layer at a predetermined depth between the exterior strengthened surface layer and the interior strengthened surface layer by irradiating the sidewall with a laser without separating the glass article.

    Abstract: A method of fabricating a high-density array of holes in glass is provided, comprising providing a glass piece having a front surface, then irradiating the front surface of the glass piece with a UV laser beam focused to a focal point within +/- 100 µm of the front surface of the glass piece most desirably within +/- 50 µm of the front surface. The lens focusing the laser has a numerical aperture desirably in the range of from 0.1 to 0.4, more desirably in the range of from 0.1 to 0.15 for glass thickness between 0.3 mm and 0.63 mm, even more desirably in the range of from 0.12 to 0.13, so as to produce open holes extending into the glass piece 100 from the front surface 102 of the glass piece, the holes having an diameter the in range of from 5 to 15 µm, and an aspect ratio of at least 20:1. For thinner glass, in the range of from 0.1 - 0.3 mm, the numerical aperture is desirably from 0.25 to 0.4, more desirably from 0.25 to 0.3, and the beam is preferably focused to within +/- 30 µm of the front surface of the glass. The laser is desirable operated at a repetition rate of about 15 kHz or below. An array of holes thus produced may then be enlarged by etching. The front surface may be polished prior to etching, if desired.

    Abstract: Disclosed herein are transparent articles and methods and systems for processing transparent articles. Systems for processing transparent articles, e.g. cutting glass, may include at least one initial laser and at least one polarizing beam splitter, where the polarizing beam splitter is configured to split an initial laser beam into a plurality of laser beams, and wherein the plurality of laser beams are useful for processing transparent articles. Methods for processing transparent articles comprise creating at least one flaw in the transparent articles with a plurality of laser beams.
