Abstract: 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 (

Abstract: A method for arresting propagation of an incident crack through a transparent material includes focusing pulsed laser beams into a laser beam focal line directed into the transparent material a series of locations corresponding to a predetermined pattern that is designed to arrest an incident crack that propagates through the transparent material, and generating, with the laser beam focal line, an induced absorption within the transparent material in order to produce a defect in the transparent material.

Abstract: 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.

Abstract: Methods are provided for laser processing arbitrary shapes of molded 3D thin transparent brittle parts from substrates with particular interest in substrates formed from strengthened or non-strengthened Corning Gorilla® glass (all codes). The developed laser methods can be tailored for manual separation of the parts from the panel or full laser separation by thermal stressing the desired profile. Methods can be used to form 3D surfaces with small radii of curvature. The method involves the utilization of an ultra-short pulse laser that may be optionally followed by a CO2 laser for fully automated separation.
