    摘要: A radiation emitter component, in particular an infrared emitter component with a conventional light-emitting diode housing, includes two electrode connections, one of which has a well-shaped reflector. The housing has an optically transparent, electrically non-conducting encapsulation material. A semiconductor laser chip is fastened in a well-shaped reflector of the light-emitting diode housing. The semiconductor laser chip has a quantum well structure, in particular with a strained layer structure, for example MOVPE epitaxial layers with a layer sequence GaAlAs-InGaAs-GaAlAs. A diffusor material can be inserted into the optically transparent, electrically non-conducting material of the light-emitting diode housing. The diffusor material is constructed or inserted with regard to type and concentration in such a way that in connection with the semiconductor laser chip encapsulated in the light-emitting diode housing, a radiation characteristic curve or an increase of an effective emission surface is produced that is comparable to that of a conventional infrared light-emitting diode.

    摘要: A laser arrangement comprises an optically pumped laser (2) and at least one semiconductor laser (1) which emits pump radiation (6) for pumping the optically pumped laser (2). The semiconductor laser (1) contains a plurality of monolithically integrated active zones (3, 4, 5) arranged one above another, at least two of the plurality of active zones (3, 4, 5) emitting pump radiation (6) of different wavelengths. In this way, it is possible to pump different absorption bands of the optically pumped laser (2) using a single semiconductor laser (1).
