Device for reducing the ablation products on the surface of a work piece during laser drilling

摘要

A device (1) for introducing holes into a workpiece (3) has a laser beam source for producing at least one laser beam (9) which may be directed toward the workpiece (3). A nozzle system (13) is provided having at least one nozzle (15; 17; 19) which may have a gas under pressure applied to it, the gas flow (23; 25; 27) exiting the nozzle (15; 17; 19) being aligned in relation to the workpiece surface in such a way that molten particles detached from the workpiece (3) are guided away from the hole produced by the laser beam (9).
