Laser processing head, especially for cutting workpiece using laser beam, has device near outlet opening between housing and laser nozzle for producing gas flow transverse to laser beam

摘要

The laser processing head has a housing (10), a laser nozzle (17) arranged on the housing near an outlet opening (12) of the housing, a focusing mirror optical system (15) that focuses the laser beam (14) through the laser nozzle to a working focus (18) and a device (16) near the outlet opening between the housing and laser nozzle for producing a gas flow transverse to the beam.
