Laser beam appts. for removing surface layers from workpieces, comprises a hand-held beam output head (11) with focusing optics (10), a light transmitting connection to a laser beam source, a beam deflection device for moving the laser beam, a tip covering the beam radially with an outlet opening on the workpiece side for the beam and a spacer for setting the distance between the output head (11) and workpiece. The spacer (14) is the tip of the output head (11); the laser beam can be oscillated by the beam deflection device over a predetermined track through the adaptable spacer outlet opening and the focusing optics (10) can vary the focusing of the beam on the workpiece surface in accordance with beam deflection. A machining process with the appts. is also claimed. USE - Used for free-hand laser beam operation, to remove surface layers from workpieces. ADVANTAGE - Allows good surface removal rates and machining times to be attained with free-hand operation.
