Abstract: The mobility of an optical processing apparatus is improved. There is provided an optical processing apparatus for scanning a processing region having an at least one-dimensional spread by moving a nozzle head while irradiating the processing region with an optical processing light beam via the nozzle head, including a light source that emits, to air, the optical processing light beam toward the nozzle head, a nozzle head that includes a hollow nozzle in a vertical direction and a light beam direction changing optical system which receives the light beam emitted from the light source and propagated in the air, and changes a propagation direction of the received light beam to a direction of a currently processed processing point in the processing region, and a main scanning direction moving mechanism that moves the nozzle head by causing the nozzle head to scan in a main scanning direction of the processing region.

Abstract: A powder convergence improves without varying the flow velocity and powder density of a powder flow. A processing nozzle includes an inner cone including a beam path that passes light from a light source, an outer cone arranged outside the inner cone, a fluid ejection channel formed by a gap between the inner cone and the outer cone, and including an ejection port that opens toward a process surface, and a fluid guide channel having a flow inlet for a fluid. The fluid guide channel guides the fluid toward the fluid ejection channel in a direction away from the beam path.
