  • Device for reducing the ablation products on the surface of a work piece during laser drilling
    Patent number: 7022941
    Abstract: A device for introducing holes into a workpiece has a laser beam source for producing at least one laser beam which may be directed toward the workpiece. A nozzle system is provided having at least one nozzle which may have a gas under pressure applied to it, the gas flow exiting the nozzle being aligned in relation to the workpiece surface in such a way that molten particles detached from the workpiece are guided away from the hole produced by the laser beam.
