Movement that includes a collective concave mirror that focuses light on the object to be cut, and defines an N-shaped optical path from the first reflecting mirror to the object to be cut via the second reflecting mirror and the collective concave mirror. The apparatus includes a freely supported optical path housing, and a condensing head that is disposed at a laser beam outlet of the optical path housing and has an assist gas outlet that blows onto the cut portion of the object to be cut, and a gap adjustment member that adjusts the diameter thereof. A laser beam cutting device characterized by:
