  • LASER PROCESSING APPARATUS AND LASER PROCESSING METHOD
    Publication number: 20150017817
    Abstract: A laser processing apparatus includes a laser beam generating device that generates a first pulse laser beam for temporarily increasing a light absorptance in a predetermined region of a processing object, and a second pulse laser beam to be absorbed in the predetermined region in which the light absorptance has temporarily increased, and a support portion that is provided on a downstream of the first pulse laser beam and the second laser beam generated by the laser beam generating device and has a placement surface for placing the processing object. The laser beam generating device emits the second pulse laser beam with a delay with respect to the first pulse laser beam by a delay time within a predetermined period of time before the light absorptance that has temporarily increased in the predetermined region returns to an original value.
