OPTICAL PROCESSING HEAD, OPTICAL MACHINING APPARATUS, AND OPTICAL PROCESSING METHOD

摘要

An optical processing head capable of downsizing an apparatus while increasing the shaping accuracy of optical processing is disclosed. The optical processing head performs processing while moving, in a predetermined moving direction on a processing surface, an optical spot formed by condensing light emitted by a light source. The optical processing head includes an optical element that condenses light emitted by the light source to generate the optical spot of a shape elongated in the moving direction of the optical spot. Part of the optical spot is set as a processing region, the front side and/or rear side of the processing region in the moving direction is set as a pre-heating region and/or post-heating region, and a processing target object before and/or after processing in the region is heated.
