Abstract

A laser processing head comprises an optical focusing unit for focusing a laser beam on a processing zone of a workpiece and an annular nozzle arranged coaxially with respect to a central axis of the laser beam for introducing an auxiliary gas into a region surrounding the processing zone. The annular nozzle is mounted on the laser processing head so as to be displaceable along the laser beam axis and can be secured to the laser processing head in different positions along the laser beam axis.
