Abstract
A laser beam is directed onto a pyramid-shaped element, wherein the beam is directed onto at least three reflecting surfaces and the respective reflected partial beams are incident on reflecting surfaces arranged on an optics carrier element. The partial beams are aligned such that they intersect in a common plane. An internal wire feed is arranged in a housing, having an outlet nozzle for a fusible wire-shaped material, which material is using the energy of the partial beams. The outlet nozzle is arranged in front of the plane in which the reflected partial beams intersect. The pyramid-shaped element and the reflecting surfaces are formed on a carrier element, which is arranged in such a way that it is displaceable following the outlet nozzle in two perpendicular directions to the optical axis of the laser beam or perpendicular to the central longitudinal axis of the wire-shaped material.
