Abstract
The present invention, among other things, relates to an apparatus (10) for working a surface (11) of a workpiece, in particular a metal workpiece, by means of laser radiation. The apparatus (10) is characterized by a scanner device (20), which is mounted in a rotationally immovable manner in the working apparatus (10) and is intended for shaping a laser beam that is to be deflected and positioned onto the surface to be worked, a control device for changing the orientation of the scanning direction of the laser beam shaped in the scanner device (20), and an optics element (40), which is movable about an axis of rotation (12), is arranged downstream of the scanner device (20) in the beaming direction of the laser beam and advantageously has a beam splitter device for splitting the laser beam into two or more beam parts (41, 42) and for deflecting and positioning the beam parts (41, 42) onto the surface (11) that is to be worked. A method for working a surface of a workpiece by means of laser radiation is also described.
