    摘要： A laser irradiation apparatus includes: multiple irradiation units each to emit a laser beam to a surface of a base to form a pattern, the multiple irradiation units, including: a first irradiation unit to emit a first laser beam; and a second irradiation unit to emit a second laser beam; and a circuitry to: control the first irradiation unit to irradiate only a first irradiation region on a surface of a base with the first laser beam; and control the second irradiation unit to irradiate only a second irradiation region on the surface of the base with the second laser beam. The first irradiation region and the second irradiation region are not overlapping each other.

    摘要： A projection optical system includes first and second optical systems. The first optical system includes a transmissive-refractive element and the second optical system includes a reflective-refractive element. An image formed by a spatial light modulator is projected by the projection optical system on a projection surface. A light beam that travels along an optical path that leads from the second optical system to the projection surface in an optical path between a center of the image formed by the spatial light modulator and the projection surface is projected at an angle with respect to a normal to the projection surface. An optical axis of the first optical system is folded to a folded position by an optical path deflecting unit in an area of the first optical system where the light beam entering the optical path deflecting unit is a converging light beam or a substantially parallel light beam.
