Title:
METHOD AND APPARATUS FOR LASER SCRIBING GLASS SHEET SUBSTRATE COATINGS
Document Type and Number:
Japanese Patent JP2010012519
Kind Code:
A
Abstract:

To provide a method for laser scribing glass sheet substrate coatings at high speed.

The method and an apparatus are provided for laser scribing coatings on glass sheet substrates by conveying the substrates adjacently to a laser source 83 which provides a pulse laser beam 84 which includes a pulse duration of at least 8 nanoseconds, a frequency of at least 50 kilohertz and a wavelength at a near infrared fundamental frequency and by reflecting the beam by an XYZ galvanometer controlled mirror system 90 toward an uncoated surface of the substrate by passing through a coating on the other surface to provide overlapping ablations through the coating so as to perform scribing at a speed of at least 1,000 mm/s.
