However, a parallel plane plate whose surface reflects visible light with a high reflectance is inserted at the Brewster angle or an angle close to the processing laser beam, and the surface reflection of the parallel plane plate causes two A parallel visible light beam is passed in parallel to the processing laser beam, at equal intervals from the processing laser beam, and at symmetrical positions with respect to the processing laser beam so as to proceed in the same direction as the processing laser beam.
