A glass container including a body having a delamination factor less than or equal to 10 and at least one marking is described. The body has an inner surface, an outer surface, and a wall thickness extending between the outer surface and the inner surface. The marking is located within the wall thickness. In particular, the marking is a portion of the body having a refractive index that differs from a refractive index of an unmarked portion of the body. Methods of forming the marking within the body are also described.

Anti-counterfeiting measures for glass articles

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 R. 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 R. 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 R, which is greater than radius of curvature R

Glass bumps on glass articles and methods of laser-induced growth

The liquid-assisted micromachining methods include methods of processing a substrate made of a transparent dielectric material. A working surface of the substrate is placed in contact with a liquid-assist medium that comprises fluorine. A focused pulsed laser beam is directed through a first substrate surface and through the opposite working surface to form a focus spot in the liquid-assist medium. The focus spot is then moved over a motion path from its initial position in the liquid-assist medium through the substrate body in the general direction from the working surface to the first surface to create a modification of the transparent dielectric material that defines in the body a core portion. The core portion is removed to form the substrate feature, which can be a through or closed fiber hole that supports one or more optical fibers. Optical components formed using the processed substrate are also disclosed.

Liquid-assisted laser micromachining systems and methods for processing transparent dielectrics and optical fiber components using same

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.

Laser processing of transparent article using multiple foci

A method for controlling formation of glass bumps in a glass article with laser-irradiation without the use of a growth-limiting structure. Standard deviation of height between the glass bumps on the article is less than 1 micron by controlling the laser radiation dose provided on the glass article.
