Abstract:
A method for laser processing a laminate workpiece stack includes forming a contour line in a first transparent workpiece of the laminate workpiece stack having a resin layer disposed between the first transparent workpiece and a second transparent workpiece. Forming the contour line includes focusing a pulsed laser beam into a pulsed laser beam focal line directed into the first transparent workpiece to generate an induced absorption within the first transparent workpiece and translating the pulsed laser beam focal line along a first workpiece separation line, thereby laser forming the contour line having a plurality of defects. The method also includes separating the resin layer along a resin separation line by focusing the pulsed laser beam into the pulsed laser beam focal line directed into the resin layer and translating the pulsed laser beam focal line along the resin separation line, thereby laser ablating the resin layer.
