Abstract
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.
