Abstract
A laser machining head for machining a workpiece by a laser beam having a housing which has an inlet opening and an outlet opening between which a passage is constructed for the laser beam through which is led a working beam pathway; focusing optics for focusing the laser beam into a working focus which is located outside the housing at a distance from the outlet opening; a sensor arrangement, and a beam deflecting device. In order to provide a laser beam machining head which, whilst having fixed and compact external dimensions, enables a simple adaptation of the sensors to the respective machining tasks, the sensor arrangement comprises a sensor module arranged in a side wall of the housing next to the laser beam through passage; and the radiation diverting device directs the radiation, coming from a zone of interaction determined by the working focus, onto sensors of the sensor arrangement so that at least one portion of the radiation can be detected for monitoring the machining of a workpiece.
