Abstract: A cleaving assembly and a method for cleaving a glass body having a face at a desired angle greater than 0 degrees are disclosed. The assembly comprises a laser device for emitting a laser beam, a rotating device, and a positioning fixture. The rotating device has a head that rotates about a central axis that is orthogonal to the laser beam. The positioning fixture is operatively mounted to the head and centered axially along the central axis and is also rotatably driven by the rotating device. The positioning fixture has a tapered surface that is transverse to the central axis and that supports the glass body at a predetermined angle relative to the central axis. Rotation of the positioning fixture about the central axis when the glass body is exposed to the laser beam, cleaves the face of the glass body at the desired angle due to the glass body being supported transverse to the central axis.

Abstract: A brittle object cutting apparatus and the method thereof are disclosed. Wherein, the brittle object cutting apparatus comprises a first heating laser unit, a second heating laser unit, a scribing laser unit, two cooling units and a processing module. A heating laser from the heating laser units respectively located on opposite sides of a scribing laser from the scribing laser unit, and a coolant of the cooling unit followed behind the heating laser. In the moving process of the brittle object, the processing module controls the scribing laser for a scribing operation, and controls one of the heating lasers and the coolant form one of the cooling units to heat and cool the brittle object. As a result, the machining time of dicing the brittle objects may be effectively reduced.

Abstract: Systems for producing articles from glass tube include a converter having a base with a plurality of processing stations and a turret moveable relative to the base. The turret indexes a plurality of holders for holding the glass tubes successively through the processing stations. The systems further include a gas flow system or a suction system for producing a flow of gas through the glass tube during one or more heating, forming, separating or piercing operations. The flow of gas through the glass tube produced by the gas flow system or suction system may be sufficient to evacuate or purge volatile constituents of the glass from the glass tube and/or pierce a meniscus formed on the glass tube during separation, thereby reducing the Surface Hydrolytic Response (SHR) of the interior surface of the glass tube and articles made therefrom.

Abstract: A method for processing glass elements is provided. The method includes introducing a perforation line for parting a glass element introduced into the glass element during or after a hot processing process at an elevated temperature of at least 100° C. Spaced-apart filamentary flaws are introduced into the glass element along the predetermined course of the perforation line by a pulsed laser beam of an ultrashort pulse laser, and, during or after the introduction of the filamentary flaws, the glass element is cooled down so as to produce a temperature gradient, which induces a mechanical stress at the filamentary flaws, whereby the breaking force required for parting the glass element along the perforation line is reduced.

Abstract: A method of producing a spiral cut transparent tube using laser machining includes using an ultrafast laser beam comprising a burst of laser pulses and focusing the laser beam on the transparent tube to enable relative movement between the laser beam and the transparent tube by moving the laser beam, the glass tube or both the laser beam and the glass tube. A beam waist is formed external to the surface of the transparent tube wherein the laser pulses and sufficient energy density is maintained within the transparent tube to form a continuous laser filament therethrough without causing optical breakdown. The method and delivery system makes a spiral cut in the transparent tube.

Abstract: Embodiments of the present method of laser cutting a laser wavelength transparent glass article comprises feeding at least one glass article to a pulsed laser assembly having at least one pulsed laser, wherein the pulsed laser defines a laser beam focal line with a length of 0.1-100 mm, the glass article being comprised of two end sections, and at least one lateral surface disposed lengthwise between the end sections. The method further comprises laser cutting at least one perforation line onto the lateral surface of the glass article while there is relative motion between the glass article and the pulsed laser and separating the glass article along the at least one perforation line to yield a laser cut glass article.

Abstract: The invention relates to a method of breaking a substrate of a brittle material, the method comprising the steps of providing a substrate (1) of a brittle material, heating the substrate with a laser beam (3) to create a heated spot on the substrate, moving the laser beam and the substrate with respect to each other to create a line of heated spots on the substrate (2), cooling the heated spots on the substrate by locally applying a cooling medium (4) behind the heated spots such that a micro-crack is propagated in the line of heated spots, and breaking the substrate along the line of the propagated micro-cracks by applying a mechanical force on the substrate wherein, the cooling medium comprises an aqueous surfactant solution. The surfactants will connect to the broken siloxane bonds inside the surface cracks. Then recombination and healing of the broken siloxane bonds will not occur and the required breaking load will remain constant over time.

Abstract: The invention seeks to provide a method of producing slices, such as semiconductor wafers, from a rod-like ingot, which does not require any cutting margin for slicing so that less material is consumed, and also is free from warping or denatured layer of the slices, as well as being free from operating environment deterioration with high quality. A cylindrical ingot is obtained by cutting or grinding the outer periphery of a rod-like ingot, and it is then formed with a plurality of annular grooves at a predetermined pitch in its longitudinal direction to obtain a cylindrical work with annular grooves. The work is then severed in the section defined by the bottom of each annular groove by generating a stress in excess of the rupture strength of the slice in the groove.After the heating of the cylindrical work with annular grooves, the under-process end face of the work is suitably cooled quickly by cooling water jet from a jet nozzle from the outer periphery toward the center of the work.
