Abstract
A method for cutting, separating and removing interior contoured shapes in thin substrates, particularly glass substrates. The method involves the utilization of an ultra-short pulse laser to form defect lines in the substrate that may be followed by use of a second laser beam to promote isolation of the part defined by the interior contour.
