Abstract
A processing apparatus using a plurality of lasers includes a plurality of laser generators that generate multiple laser beams, a plurality of beam modifiers that maintain a shape of each laser beam or modify the shape in real time, beam combiners that combine multiple laser beams modified by the plurality of beam modifiers, and a control unit that changes an irradiation condition of each laser beam based on a processing condition of an object to be processed to control driving of each laser generator and the beam modifier in real time, thereby irradiating laser beams having different wavelengths to a single object to be processed or an object to be processed in which the same or different materials are stacked to process the single object to be processed or the object to be processed.
