In a method, substrate elements are provided wherein each substrate element has a first side and a second side meeting at a corner point. The substrate elements are picked and then placed on a support device in alignment. A cutting operation is then performed where each of the substrates elements are cut along a cut line having a common first direction which intersects the first and second sides of each of the substrate elements in order to create a third side on each substrate element. The third side of each of the substrate elements meets the first and the second sides at corresponding corner points.

A method for processing a transparent workpiece that includes directing a laser beam the transparent workpiece. The laser beam incident to the impingement surface has an oblong angular spectrum and portion of the laser beam directed into the transparent workpiece is a laser beam focal line and generates an induced absorption to produce a defect within the transparent workpiece. The laser beam focal line includes a wavelength λ, a spot size w.sub.o, a Rayleigh range Z.sub.R that is greater than $F_D\frac{\pi w_o^2}{\lambda },$
where F.sub.D is a dimensionless divergence factor comprising a value of 10 or greater, and an internal beam angle of greater than 10° relative to a plane orthogonal to an impingement surface at an impingement location, such that the defect has a defect angle within the transparent workpiece of greater than 10° relative to a plane orthogonal to the impingement surface at the impingement location.

Systems and processes of cutting and drilling in a target substrate uses a laser (e.g., a pulsed laser) and an optical system to generate a line focus of the laser beam within the target substrate, such as a glass substrate sheet, are provided. The laser cutting and drilling system and process creates holes or defects that, in certain embodiments, extend the full depth of the glass sheet with each individual laser pulse, and allows the laser system to cut and separate the target substrate into any desired contour by creating a series of perforations that form a contour or desired part shape. Since a glass substrate sheet is brittle, cracking will then follow the perforated contour, allowing the glass substrate sheet to separate into any required shape defined by the perforations.

A laser apparatus and a method for manufacturing a display device are provided. A laser apparatus includes: a stage; a laser providing unit above the stage and configured to provide a laser beam; a scanner configured to adjust an optical path of the laser beam such that the laser beam is irradiated to an irradiation line formed above the stage; and a control unit to control an operation of the scanner, and the scanner includes a shutter located on an optical path of the laser beam emitted from the laser providing unit and configured to perform an opening/closing operation.

A method of manufacturing a coated glass article that includes (i) preparing a glass substrate having a first and second opposed main surfaces, (ii) irradiating at least the first main surface of the glass substrate with a laser to form at least one separating line defining contour lines, for dividing at least one glass article from the glass substrate, the glass article having a shape and/or size different from the glass substrate of step (i), (iii) chemically strengthening the glass substrate on which at least one separating line is formed, the separating line extending in a depth direction from the first main surface to the second main surface, and (iv) separating of the at least one glass article from the glass substrate according to the at least one separating line. In addition, the glass substrate is coated between steps (iii) and (iv).

A method of cutting a glass sheet comprising a transparent oxide glass includes directing a laser beam from a middle-infrared (mid-IR) laser source onto a major surface of the glass sheet. A wavelength of the laser beam is tuned thereby adjusting an absorption depth of the laser beam in the glass sheet. The glass sheet is cut using the laser beam.

A method for cutting, separating and removing interior contoured shapes in thin substrates, particularly glass substrates. The method involves the utilization of an ultra-short pulse laser to form defect lines in the substrate that may be followed by use of a second laser beam to promote isolation of the part defined by the interior contour.

A glass tube is treated with laser cutting for separating a hollow glass body from the glass tube. A laser beam used for laser cutting is focused on a wall of the glass tube.

An element of an inorganic brittle material having two opposed sides and a circumferential edge includes at least three sections. The at least three sections include a first section and two second sections, the second sections adjoining the first section so that the first section is arranged between the second sections. The first section includes an arrangement of openings forming passages from one side to an opposed side of the element so that the first section has a higher flexibility than the second sections.
