Abstract
A method and apparatus for splitting non-metallic substrates includes a laser for generating a laser beam. An integrated cracking devices receives the laser beam and directs the laser beam onto a non-metallic substrate to define the heat affected zone and quench the substrate at a quenching region contained within the heat affected zone. This integrated cracking device includes a housing and optics fitted within the housing for receiving and directing the laser beam onto the substrate. A quenching nozzle is mounted on the housing for quenching the substrate at a quenching region defined within the heat affected zone.
