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.
