摘要： 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.

摘要： A light generating apparatus is operably coupled to an optical fiber (10) with a cladding (5) and a core (4) defining a core diameter. The optical fiber (10) has a numerical aperture, and the product of the numerical aperture of the fiber and one-half the diameter of the core (4) is less than or substantially equal to 400 millimeter-milliradians. The apparatus includes a plurality (7) of laser diode arrays (6, 23, 55), each array comprising at least one light emitting region (1, 24) adapted for emitting light in a individual beam (21, 11). The plurality of laser diode arrays (6, 23, 55) are arranged such that light from the individual beams (21, 11) is combined in a combined beam, and the combined beam has a first far-field, half-angle divergence in a first direction and a first waist dimension in the first direction, and a second far-field, half-angle divergence in a second direction, substantially perpendicular to the first direction, and a second waist dimension in the second direction. The laser diode arrays (6, 23, 55) are arranged relative to the optical fiber (10) to couple light output from the laser diode arrays (6, 23, 55) into the core of the fiber at an end of the fiber. The product of the first far-field, half-angle divergence and the first waist dimension is equal to or smaller than one-half of the product of the core diameter and a numerical aperture of the fiber (10), and the product of the second far-field, half-angle divergence and the second waist dimension is equal to or smaller than one-half of the product of the core diameter and the numerical aperture.
