Publication number: 20150166391Abstract: The present disclosure relates to a process for cutting and separating arbitrary shapes of thin substrates of transparent materials, particularly tailored composite fusion drawn glass sheets, and the disclosure also relates to a glass article prepared by the method. The developed laser method can be tailored for manual separation of the parts from the panel or full laser separation by thermally stressing the desired profile. The self-separation method involves the utilization of an ultra-short pulse laser that can be followed by a CO2 laser (coupled with high pressure air flow) for fully automated separation.Type: ApplicationFiled: October 31, 2014Publication date: June 18, 2015Inventors: Sasha Marjanovic, Garrett Andrew Piech, Sergio Tsuda, Robert Stephen Wagner

Publication number: 20150165562Abstract: A method of laser processing a material to form a separated part. The method includes focusing a pulsed laser beam into a laser beam focal line, viewed along the beam propagation direction, directed into the material, the laser beam focal line generating an induced absorption within the material, the induced absorption producing a hole or fault line along the laser beam focal line within the material, and directing a defocused carbon dioxide (CO2) laser from a distal edge of the material over the plurality of holes to a proximal edge of the material.Type: ApplicationFiled: October 31, 2014Publication date: June 18, 2015Inventors: Sasha Marjanovic, Garrett Andrew Piech, Sergio Tsuda, Robert Stephen Wagner

Publication number: 20150166393Abstract: This laser cutting process makes use of a short pulse laser in combination with optics that generate a focal line to fully perforate the body of a range of ion-exchangeable glass compositions. The glass is moved relative to the laser beam to create perforated lines that trace out the shape of any desired parts. The glass may be cut pre-ion exchange, or may be cut post-ion exchange. The laser creates hole-like defect zones that penetrate the full depth the glass, of approximately 1 micron in diameter. These perforations or defect regions are generally spaced from 1 to 15 microns apart.Type: ApplicationFiled: October 31, 2014Publication date: June 18, 2015Inventors: Sasha Marjanovic, Garrett Andrew Piech, Sergio Tsuda, Robert Stephen Wagner

Publication number: 20150165548Abstract: 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: October 31, 2014Publication date: June 18, 2015Inventors: Sasha Marjanovic, Albert Roth Nieber, Garrett Andrew Piech, Helmut Schillinger, Sergio Tsuda, Robert Stephen Wagner

Patent number: 8943855Abstract: A method of cutting an article (172) from a chemically strengthened glass substrate (110) includes generating a pulsed laser beam (108) from a laser source (106). The pulsed laser beam (108) may have a pulse duration of less than about 1000 fs and an output wavelength such that the chemically strengthened glass substrate (110) is substantially transparent to the pulsed laser beam (108). The pulsed laser beam (108) may be focused to form a beam waist (109) that is positioned in the same horizontal plane as an inner tensile region (124) of the chemically strengthened glass substrate (110). The beam waist (109) may be translated in a first pass along a cut line (116), wherein the beam waist (109) traverses an edge (111) of the chemically strengthened glass substrate. The beam waist (113) may then be translated in a second pass along the cut line (116) such that a crack (119) propagates from the edge (113) along the cut line (116) ahead of the translated beam waist (109) during the second pass.Type: GrantFiled: August 27, 2010Date of Patent: February 3, 2015Assignee: Corning IncorporatedInventors: Sinue Gomez, Lisa Anne Moore, Sergio Tsuda
