Abstract
The present invention relates to a process for cutting and separating interior contours in thin substrates of transparent materials, in particular glass. The method involves the utilization of an ultra-short pulse laser to form perforation or holes in the substrate, that may be followed by use of a COlaser beam to promote full separation about the perforated line.
