LASER PROCESSING APPARATUS AND LASER PROCESSING METHOD

摘要

A laser processing apparatus is provided with a laser oscillator which outputs a continuous wave or pulse wave thermal processing laser beam or a pulse wave surface processing laser beam; a light inputting optical system for inputting a laser beam outputted from the laser oscillator into an optical fiber; a collecting lens for collecting laser beams outputted from an optical fiber; and a processing apparatus which has the collecting lens mounted thereon, moves close to an object to be processed, and applies laser beams to the surface of the object to be processed. The laser oscillator outputs the thermal processing laser beams for thermal processing, and outputs surface processing laser beams for pre-processing or post-processing of the thermal processing.
