Abstract: Methods of manufacturing a ribbon can comprise identifying a location of a nonuniformity in a characteristic of a molten portion of a moving ribbon. The methods can further comprise impinging a deflected pulsed laser beam on a heating zone comprising a location of a nonuniformity in the molten portion of the ribbon. In some embodiments, the heating zone can be elongated in a travel direction of a travel path of the moving ribbon. In some embodiments, the pulsed laser beam can be reflected off a reflective surface of a polygonal reflecting device rotating at a substantially constant angular velocity. In some embodiments, the methods can include impinging the deflected pulsed laser beam on a sensing device to generate a signal. The methods can further comprise calibrating a location of the deflected pulsed laser beam based on the signal from the sensing device.

Abstract: A method for processing a transparent workpiece includes forming a contour of defect in the transparent workpiece and separating the transparent workpiece along the contour using an infrared laser beam. During separation, the method also includes detecting a position and propagation direction of a crack tip relative to a reference location and propagation direction of an infrared beam spot, determining a detected distance and angular offset between the crack tip and the reference location of the infrared beam spot, comparing the detected distance to a preset distance, comparing the detected angular offset to a preset angular offset, and modifying at least one of a power of the infrared laser beam or a speed of relative translation between the infrared laser beam and the transparent workpiece in response to a difference between the detected distance and the preset distance and between the detected angular offset and the preset angular offset.

Abstract: A system and method for making an edge section of a thin, high purity fused silica glass sheet. The method includes a step of directing a laser to melt through the glass sheet with localized heating of a narrow portion of the glass sheet to form an edge section of the glass sheet, and continuing the edge section to form a closed loop defining a perimeter of the glass sheet. The method further includes rapidly cooling the glass sheet through the glass transition temperature as the melted glass of the edge section contracts and/or solidifies to form an unrefined-bullnose shape extending between first and second major surfaces of the glass sheet.
