  • Method and apparatus for laser scribing glass sheet substrate coatings
    Patent number: 6919530
    Abstract: A method and apparatus (42) for laser scribing coatings on glass sheet substrates by conveying the substrate adjacent a laser source (83) that provides a pulsed laser beam (84) with a wavelength at a near-infrared fundamental frequency and having a frequency in the range of 50 to 100 kilohertz and a pulse duration in the range of 8 to 70 nanoseconds, and by reflecting the beam by an XYZ galvanometer controlled mirror system (90) toward an uncoated surface of the substrate for passage therethrough to the coating on the other surface to provide overlapping ablations through the coating and scribing at a speed of at least 1000 millimeters per second.
    Type: Grant
    Filed: April 30, 2003
    Date of Patent: July 19, 2005
    Assignee: First Solar LLC
    Inventors: Frank A. Borgeson, Joseph J. Hanak, Karen M. Harju, Norman L. Helman, Kenneth R. Hecht, Ricky S. Harju
