Abstract:

A method includes forming, by a laser beam supplied by a laser cutting system, a laser-cut line in each of a plurality of glass samples. Each different laser-cut line in each different glass sample of the plurality of glass samples is formed when the laser cutting system is at a different process setting. The method also includes subjecting each of the plurality of glass samples with the laser-cut lines to a break test, and obtaining a plurality of break strength values. Each different break strength value of the plurality of break strength values is indicative of a laser-cut line quality of the respective glass sample of the plurality of glass samples.
