Problems solved by technology

However, conventional laser processing utilizes a laser beam that travels in a straight line in free space, so it is difficult to use a laser beam when a circular outer edge or similar edge shape is required

Abstract

Systems and methods utilizing two Airy beams to process a non-rounded edge of a glass substrate or to cleave a glass substrate are disclosed. The method includes generating first and second Airy beamsand causing them to cross at a crossing to define a curved intensity profile in the vicinity of the crossing point where the first and second Airy beams have respective local radii of curvature RA and RB. The method also includes scanning the curved intensity profile either along the non-rounded outer edge or through the glass along a scan path to form on the glass substrate a rounded outer edgehaving a radius of curvature RE that is smaller than the first and second local radii of curvature RA and RB. The radius of curvature RE can be adjusted by changing a beam angle between the first andsecond Airy beams.

Description

[0001] This application claims priority to US Patent Provisional Application No. 62 / 278,657, filed January 14, 2016, the contents of which are the basis of this application and are incorporated herein by reference in their entirety. technical field [0002] The present disclosure relates to glass processing; and in particular, to systems and methods for processing glass substrates using dual Airy beams. Background technique [0003] Glass processing, including glass cutting (cleavage) and edge trimming, is important in the formation of glass articles such as display glass, glass panels, and cover glass. In particular, the square edges of glass sheets are prone to breakage and may be beveled or rounded to minimize the possibility of breakage. This can be done using mechanical means such as mechanical grinding. Likewise, glass substrates need to be cleaved to have a selected size and shape. This can also be done using mechanical means such as using a diamond knife saw. Unfo...
