Abstract: A device and a method for beam shaping and beam movement during laser material processing with a laser beam source (1) for continuously emitting a laser beam (2), a first optical deflection element (3), a second optical deflection element (4), and an optical focusing element (5) arranged between the second optical deflection element (4) and a workpiece surface (7) to be processed. The second optical deflection element (4) is configured to displace a point of incidence of the laser beam (2) on the workpiece surface (7), and the first optical deflection element (3) is configured to alter a position of a focal plane of the laser beam (2) relative to the workpiece surface (7) by means of a translational movement and/or to change an intensity distribution within a beam cross section of the laser beam.

Abstract: The invention relates to a method for the manufacture of a bioreactor or of a lab-on-a-chip system as well as to bioreactors or lab-on-a-chip systems manufactured therewith. In this respect, at least two different components are connected to one another. It is the object of the present invention to set forth a method with which bodies having very different melting points, namely a ceramic material and a polymer, can be connected to one another independently of whether the surfaces to be connected are accessible from the outside or not. In the method in accordance with the invention, a first body made from a polymer which is at least partially transparent for electromagnetic radiation of at least one wavelength ?, and a second body made from a ceramic material which absorbs electromagnetic radiation of the at least one wavelength ? are connected to one another. The first body is at least regionally meltable.

Abstract: A method for producing a brazed joint having at least one of a metal/ceramic joint and a ceramic/ceramic joint. The method includes forming bores in at least one ceramic surface to be brazed, and the bores have an average diameter of greater than 550 ?m. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Abstract: 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.
