ABSTRACT:
A highly accurate structure is optically fabricated simply and in a short time. Rough optical fabrication using an ultraviolet-irradiation optical fabrication process is carried out for a photo-curing resin by emission of a laser beam from a first light source, and thereafter, fine optical fabrication using a two-photon absorption optical fabrication process is carried out by emission of a laser beam from a second light source. As a result, it is possible to realize optical fabrication which allows fabrication of a fine structure using a two-photon absorption optical fabrication process while realizing high speed processing using the ultraviolet-irradiation optical fabrication process.
