Abstract
A method and apparatus ( ) for laser scribing coatings on glass sheet substrates by conveying the substrate adjacent a laser source ( ) that provides a pulsed laser beam ( ) 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 ( ) 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.
