Jet nozzle having an absorption portion for absorbing back-reflected radiation

Abstract

A jet nozzle for laser cladding along a direction of advance includes a light channel for conducting at least one laser beam directed onto a workpiece, and an outer structure surrounding the light channel at least in sections. The outer structure extends from a flange portion to a distal region that is formed by a mouth of the jet nozzle from which the at least one laser beam exits. The light channel forms an absorption portion for absorbing back-reflected radiation of the at least one laser beam from the workpiece.
