  • Patent number: 11612955
    Abstract: A joining device and method for laser-based joining of two components includes a first laser radiation source, a first radiation guide connected to the first radiation source to couple first laser radiation into the first radiation guide, a second laser radiation source, at least one second radiation guide connected to the second radiation source to couple second laser radiation into the second radiation guide, and a focusing device coupled to the laser radiations and focusing them at a distance from each other into a joining zone of the components. To reduce installation effort, the focusing device focuses the first and second laser radiations through a common beam path and a coupling device is connected on its input side to the first and second radiation guides and on its output side to the focusing device. The coupling device couples the first and second laser radiations into the common beam path.

  • Publication number: 20220339741
    Abstract: 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. The technical result is: improved strength parameters of products and better quality of straight and oblique edges formed during substrate cleaving, absence of chips and microcracks, high rate of formation of the stressed cleaving edge, which implies faster laser cutting.
