DEVICE FOR REDUCING THE ABLATION PRODUCTS ON THE SURFACE OF A WORK PIECE DURING LASER DRILLING

摘要

The invention relates to a device (1) for introducing holes in a work piece (3), which comprises a laser radiation source for producing at least one laser beam (9) that is directed onto the work piece (3). The inventive device is provided with a nozzle arrangement (13) comprising at least one nozzle (15; 17; 19) that can be impinged upon by a pressurized gas. The gas flow (23; 25; 27) emerging from the nozzle (15; 17; 19) is oriented with respect to the surface of the work piece in such a manner that molten particles that have been removed from the work piece (3) are discharged from the hole that is produced by the laser beam (9).
