Publication number: 20220339741Abstract: The invention relates to laser equipment, specifically pulsed scanning lasers used to cut brittle substrates. The authors propose a method and device for forming a stressed edge in the substrate for cleaving of the substrate, to which end a track of cavities is formed through optically induced breakdown in the body of tire material during its irradiation with a focused laser beam with a fixed focal distance during the course of angled scanning of the laser beam, with longitudinal movement along the length of the substrate.

Patent number: 11458566Abstract: Systems, methods and apparatuses are used for monitoring material processing using imaging signal density calculated for an imaging beam directed to a workpiece or processing region, for example, during inline coherent imaging (ICI). The imaging signal density may be used, for example, to monitor laser and e-beam welding processes such as full or partial penetration welding. In some examples, the imaging signal density is indicative of weld penetration as a result of reflections from a keyhole floor and/or from a subsurface structure beneath the keyhole. The monitoring may include, for example, automated pass/fail or quality assessment of the welding or material processing or parts produced thereby. The imaging signal density may also be used to control the welding or material processing, for example, using imaging signal density data as feedback. The imaging signal density may be used alone or together with other measurements or metrics, such as distance or depth measurements.Type: GrantFiled: December 19, 2019Date of Patent: October 4, 2022Assignee: IPG PHOTONICS CORPORATIONInventors: Christopher M.
