摘要： A method for detecting Raman scattered light using at least one interference filter and a detection unit, the Raman scattered light to be detected including an incoming scattered light signal, wherein the method includes the following steps: * a first filtered scattered light signal is generated by the application of a first transmission function to the incoming scattered light signal, the first transmission function being assigned to a first optical path length L1 through a first interference filter, and the first transmission function defining a first spectral band δλ1; * a second filtered scattered light signal is generated by the application of a second transmission function to the incoming scattered light signal, the second transmission function being assigned to a second optical path length L2≠L1 through the first interference filter or through a second interference filter, and second transmission function defining a second spectral band δλ2; and * the first and the second filtered scattered light signals are detected by the detection unit.

摘要： The invention relates to an optical waveguide with two or more light-guiding cores (1a-1e) extending continuously along the longitudinal extension of the optical waveguide, parallel to one another and spaced apart from one another, from one end of the optical waveguide to the other, and with a first cladding (2) enclosing the cores (1a-1e). It is an object of the invention to provide a multicore optical waveguide for high-power operation with reduced system complexity compared to the prior art. This object is achieved by the invention in that the cores (1a-1e) are arranged relative to one another and are spaced apart from one another in such a way that the propagation modes of the light propagating in the optical waveguide at a working wavelength couple to one another, the length of the optical waveguide being selected such that the light coupled into only a single one of the cores (1a-1e) at one end of the optical waveguide first spreads to the other cores (1a-1e) during propagation through the optical waveguide and, after passing through the optical waveguide, leaves the optical waveguide again at the other end from a single core (1a) with at least 60%, preferably at least 75%, of the total light power propagating in the optical waveguide. The invention also relates to a laser system with such an optical waveguide as an optical amplifier, and a method for guiding light in an optical waveguide.

摘要： Device with an electrode arrangement with a plurality of electrodes for measuring electric signals on a face surface of a head of a user and behind an ear of the user; and with a carrier structure. The carrier structure at least partially defines a relative position of the electrodes to one another, and the carrier structure is shape-stable within a tolerance range without external force exerted by a user and deformable under external force exerted by the user, in order to change a distance between two adjacently arranged electrodes and/or to area-comprehensively adapt to face and head structures. The carrier structure is configured to position at least a part of the electrode arrangement on the face surface and behind the ear.

摘要： A method is provided for smoothing a surface region of a component consisting of an electrically conductive material. The surface region of the component is coated inside a vacuum chamber, by focused electron beam(s) with a first surface energy, which brings about melting of the component material within the surface region. Before melting, the surface region is passed over at least twice by the electron beam, each time with a different focal length of the electron beam. A second surface energy is set for the electron beam, such that no melting of the component material is brought about in the surface region. Data is recorded by a number of sensors arranged inside the vacuum chamber. An actual value for the roughness is compared to a set point value. If the actual value has not reached the set point value, a value for the first surface energy is determined via comparison.
