Abstract
Described is laser machining nozzles for laser machining devices. The laser machining nozzles includes a body having an inner surface and an outer surface. The inner surface of the laser machining nozzles include at least one subarea. The subarea includes a layer of at least one of the copper oxides CuO and Cu2O. The layer of CuO and/or Cu2O has an absorbing effect for radiation at an observation wavelength between 300 and 1100 nm or between 900 and 1700 nm.
Claims8
A laser machining nozzle for a laser machining device, the laser machining nozzle comprising a body comprising an inner surface and an outer surface,
- wherein the inner surface of the laser machining nozzle comprises at least one contrast section that is directly formed on the inner surface,
- wherein the contrast section directly adjoins a nozzle opening of the laser machining nozzle facing a workpiece, and
- wherein the contrast section comprises a scattering surface structure that has a surface roughness that provides a scattering effect for radiation at an observation wavelength between 300 and 3000 nm.
