Claims

[Claims for Utility Model Registration] A laser that makes a laser beam transmitted through an optical fiber enter a rectangular waveguide and causes the beam to have a uniform rectangular intensity distribution by causing multiple reflections within the rectangular waveguide. In a beam shaping device for use with a laser beam, one end surface of an optical fiber is brought into contact with one end surface of a rectangular waveguide so that the laser beam is directly incident on the rectangular waveguide, and the beam shaping device is made uniform by the rectangular waveguide. A laser beam shaping device characterized by having an optical system for enlarging/reducing a beam to an appropriate magnification and a rectangular waveguide axis deviation/sag adjustment device.
