A component includes a glass or glass ceramic having a thickness and a plurality of predamages. Each predamage of the plurality of predamages has a longitudinal axis and passes continuously through the thickness of the glass or the glass ceramic. The component also includes a material compaction of the glass or glass ceramic that is at least 1% relative to an actual material density in a radius of 3 μm about the longitudinal axis of each predamage so that the glass or the glass ceramic has a relative weight loss per predamage that is less than 10%.

Components made of glass or glass ceramic having predamage along predetermined dividing lines

A method of structuring a glass element having a first side face and a second side face is provided. The method includes the steps of: producing a filament-shaped flaw in the glass element with a pulsed laser beam along a focus line; etching to remove glass in the filament-shaped flaw to form a wall extending from the first side face towards the second side face, the wall having a boundary line that is tapered at a vertex between the wall and the first side face with a taper angle with respect to a perpendicular of the first side face; and adjusting the taper angle by controlling a feature of the focus line. The feature is selected from a group consisting of a position of the focus line, a length of the focus line, an intensity distribution of the focus line, and any combinations thereof.

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.

A component of glass or glass ceramic having predamages arranged along at least one predetermined dividing line is provided. The dividing line has a row of predamages lying one behind the other. The predamages pass continuously through the glass or the glass ceramic with at least 90% of the predamages being cylindrically symmetrical. The glass or the glass ceramic has a material compaction of at least 1% relative to an actual material density in a radius of 3 μm about a longitudinal axis of respective pre-damaged points. The relative weight loss per pre-damaged point is less than 10% and the component has a thickness of at least 3.5 mm.

A method and apparatus for producing glass products from tubular glass precursors is provided. In particular, a method and apparatus for separating tube glass into sized glass tube portions, produced glass tube portions, glass precursor portions, or glass product portions, and their use as pharmaceutical packaging are provided. The tube glass or the glass precursor or the glass product is provided with filaments along predetermined breaking planes. The filaments extend obliquely to the local wall radius and allow for clean separation of the tube glass or the glass precursor or the glass product.

The invention relates to a system for treating gases and/or liquids with radiation or for detecting radiation in gases and/or liquids, including at least one optical system and a reactor. The reactor has a hollow body shape which includes lateral surfaces, connecting parts, and an inner chamber which may be open to the front and rear sides, through which a medium flows or in which the medium is present. The reactor is designed, at least partially, in the form of a radiation reflector and is divided into first and second functional areas. This enables a particularly homogeneous radiation distribution in the inner chamber of the reactor, which increases the efficiency of the treatment or detection. Also, due to this arrangement, the system is more compact.
