A method of cutting glass with a laser, and methods produced according glass product

2015 
The invention has the object to improve process stability when cutting very thin glasses. For this purpose a method for separating sheet glass (1) having a thickness, it is proposed less than 250 microns, warmed wherein the thin glass (1) along a a dividing line (3) forming path along a feed direction (103) proceeding with a laser beam (8) is, so that a crack (7) propagates along the dividing line (3) and the thin glass (1) is cut, wherein the laser beam (8) by means of a Strahlformumgsoptik (6) is formed so that its beam profile (80) an elongate shape and wherein the laser beam (8) onto the surface of the thin glass (1) is directed such that its longitudinal direction (81) is located in the feed direction, and wherein the elongated shape of the beam profile is asymmetric, so that the intensity profile (at the ends 82, 83) of the beam profile (80) is different such that the increase in the intensity at which the thin glass (1) first passing over the front end (82) is steeper than the decrease in the intensity of the ge genuberliegenden rear end (83).
