Publication number: 20180044219Abstract: Processes of chamfering and/or beveling an edge of a glass or other substrate of arbitrary shape using lasers are described herein. Three general methods to produce chamfers on glass substrates are disclosed. The first method involves cutting the edge with the desired chamfer shape utilizing an ultra-short pulse laser. Treatment with the ultra-short laser may be optionally followed by a CO2 laser for fully automated separation. The second method is based on thermal stress peeling of a sharp edge corner, and it has been demonstrated to work with different combination of an ultrashort pulse and/or CO2 lasers. A third method relies on stresses induced by ion exchange to effect separation of material along a fault line produced by an ultra-short laser to form a chamfered edge of desired shape.Type: ApplicationFiled: July 26, 2017Publication date: February 15, 2018Inventors: Sasha Marjanovic, Albert Roth Nieber, Garrett Andrew Piech, Helmut Schillinger, Sergio Tsuda, Robert Stephen Wagner

Patent number: 9850160Abstract: The present invention relates to a laser cutting technology for cutting and separating thin substrates of transparent materials, for example to cutting of display glass compositions mainly used for production of Thin Film Transistors (TFT) devices. The described laser process can be used to make straight cuts, for example at a speed of >1 m/sec, to cut sharp radii outer corners (<1 mm), and to create arbitrary curved shapes including forming interior holes and slots. A method of laser processing an alkaline earth boro-aluminosilicate glass composite workpiece includes focusing a pulsed laser beam into a focal line. The focal line is directed into the glass composite workpiece, generating induced absorption within the material. The workpiece and the laser beam are translated relative to each other to form a plurality of defect lines along a contour, with adjacent defect lines have a spacing of 0.1-20 microns.Type: GrantFiled: October 31, 2014Date of Patent: December 26, 2017Assignee: Corning IncorporatedInventors: Sasha Marjanovic, Albert Roth Nieber, Garrett Andrew Piech, Helmut Schillinger, Sergio Tsuda, Robert Stephen Wagner
