    摘要: In machining a workpiece, maximal absorption of laser irradiation in the workpiece is achieved by a minimal interference by optical back-coupling and plasma effects is achieved by continuously determining the actual value of the laser irradiation and continuously sensing stochastic processes taking place in the machining zone and in response to such measuring and sensing, controlling the modulation of laser irradiation.

    摘要: A waveguide is arranged in radial extension on a support mounted in rotary manner and whose pivot pin is parallel to the laser beam axis. The outer end thereof intersects the laser beam during a rotation of the support and in each case detects a partial beam of the laser radiation. By means of the waveguide, said partial beam is supplied to a detector, which is arranged in fixed manner in the pivot pin of the support. A hollow waveguide or light guide serves as the waveguide. A parallel displacement of the pivot pin of the support is possible by means of a stepping motor to enable the complete beam profile to be determined by a plurality of sections through the laser beam. In place of the stepping motor, the support can be provided with several waveguides of different lengths, distributed with the same angular spacing over the support circumference and which successively supply the detected partial beams to the same detector.

    摘要: The invention relates to a device and method for structuring the surface of floor coverings which have already been laid, comprising various floor coverings which may also consist of mineral materials such as natural or artificial stone. The object of the invention is to provide floor coverings which have already been laid with a structure on their surface, which structure makes it possible to at least increase the nonslip properties even in the presence of slippy media, e.g. water. To do this, the invention uses a device with which at least one laser beam can be moved with controlled intensity and in at least one dimension across the surface to be structured, the elements for guiding and shaping the laser beam(s) being accommodated in a mobile part of the device, so that this mobile part is guided intermittently or continuously across the floor surface which is to be structured and, in the process, the structuring can be formed by means of the laser beam.

    摘要: The invention relates to a method and a device for laser-beam welding, because the invention is especially suitable for deep welding a wide variety of materials. The object of the invention is to weld a wide variety of materials by means of laser radiation, especially by deep welding, with a reduced amount of work and at the same time good quality of the welded joint produced. The procedure adopted for this according to the invention is that the intensity of the laser radiation is set by beam-shaping in and on the surface of workpieces in such a way that a small area in the workpiece is irradiated with a great intensity, to form a steam capillary there, and a further, larger adjacent area on the workpiece surface is irradiated with a lesser intensity, and as a result a bell-shaped opening of the steam capillary is formed on the workpiece surface and the cooling rate of the melted material is reduced.

    摘要: A device for plating two or more metal plates, strips, etc., by the absoron of laser energy. The device is fitted with beam-forming optics which form the laser radiation into a beam with a rectangular cross-section. The radiation source is a laser-diode array in which several laser diodes are disposed next to each other in the same plane to give bars which can be laid next to each other, as well as stacked one on top of each other, in any numbers. In order to homogenize the laser radiation produced by the array to give a rectangular cross-section, the device proposed is fitted with special optics such as a prism which converges in the shape of a wedge, a glass plate, with a rectangular cross-section, reflective boundary drives, etc. The rectangular cross-section beam heats the two surfaces of the metal plates being plated only locally, over limited areas and to small depths, to the plastic state. In addition, sensors and control devices for control of the power of the laser-diode array and/or for changing the speed of advance of the metal plates being plated may be used.
