  • Laser machining nozzle for a laser machining device, and laser machining device
    Patent number: 11440135
    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.
