Abstract: Methods of using a laser to separate a glass sheet is presented that employs an elongated and, preferably, asymmetrically-truncated laser beam. The methods allow glass sheets suitable for use in modern display applications to be separated at speeds up to about 200 mm/s with low levels of residual stress, e.g., levels of residual stress which are less than or equal to 100 psi, and preferably less than 50 psi. Glasses with high coefficients of thermal expansion (e.g. greater than about 35×10?7/° C.) maybe separated at faster speeds. Such low levels of residual stress translate into low levels of distortion during the manufacture of display panels (e.g., LCD panels) as well as in improved properties (geometry, strength, defect-free etc.) of the separated edges. The methods can be used with glasses of various types including glasses having high coefficients of thermal expansion and also with glass sheets of different thickness.
