Abstract: A method of separating a coated substrate includes directing an infrared laser beam onto a first surface of the coated substrate. The coated substrate includes a coating layer disposed on a transparent workpiece, a plurality of defects is disposed within the coated substrate along a contour line that divides a primary region from a dummy region of the coated substrate from a dummy region of the coated substrate. The method also includes translating at least one of the coated substrate and the infrared laser beam relative to each other such that an infrared beam spot traces an oscillating pathway that follows an offset line in a translation direction and oscillates between an inner and outer track line, the oscillating pathway is disposed on the dummy region of the coated substrate, and the infrared laser beam applies thermal energy to the plurality of defects to induce separation of the coated substrate.

Abstract: A glass article including a glass substrate with outer edges defining an outer profile and an optical film layer bonded to the glass substrate at a peripheral bonding zone located inward of the outer edges of the glass substrate. The glass article can be produced by directing laser energy at the glass article to simultaneously trim the optical film layer to a predetermined size while bonding the optical film layer to the glass substrate.
