A laser beam apparatus for the removal of surface layers from work pieces with a beam-emitting head that may be guided by hand and that is equipped with focusing optics, which is connected to laser apparatus that generates a laser beam so as to admit light, which exhibits a beam-deflecting direction that moves on a pre-determined pathway in an oscillating manner, which covers the laser beam radially with a point and releases it through an emission opening that faces the work piece, and which has a distance retainer that permits the adjustment of the distance of the beam-emitting head from the work piece. In order to achieve the possibility of its use under freehand guidance with great mean power outputs in the course of which acceptable area coverage rates, or rather processing times are to be rendered possible, the laser beam apparatus is embodied in such a way that the distance retainer is the point of the beam-emitting head that covers the laser beam radially, that the laser beam may be oscillated by the beam deflection apparatus on a pre-determined pathway by means of an exit opening of the distance retainer that has been adapted to the pathway, and that the focusing optics can alter the focusing of the laser beam depending upon the beam deflection in the sense of a focus that lies on the surface of the work piece.
