Abstract:
A laser beam apparatus for removing surface layers from workpieces, said apparatus comprising:a beam emitting head (11) capable of being guided by hand and provided with focusing optics (10),a laser apparatus (13,25,26) for feeding light, to said focusing optics,a beam deflection apparatus (22) disposed in said head (4) and that moves the laser beam (12);a housing which covers the laser beam (12) and releases said laser beam through an exit opening (33) toward the workpiece, and a distance retainer (14) that renders the distance of the beam emitting head (11) from the workpiece adjustable,characterized by the fact that the distance retainer (14) is a portion of the laser beam apparatus which covers the laser beam (12) and which may be supported on the workpiece so as to seal it off, that the laser beam (12) is capable of being oscillated by the beam deflection apparatus (22) on a predetermined pathway by means of (an outlet) an exit opening of the distance retainer (14), and that the focusing optics (10) can alter the focus of the laser beam (12), depending upon the deflection of the beam, with a focus that lies on the surface of the workpiece.
