Abstract: A semiconductor laser assembly has at least one semiconductor laser which is designed to emit laser radiation through an exit area and at least one further area, the further area being a part of a surface of the semiconductor laser and/or of the semiconductor laser assembly and the further area is developed to be reflecting to the radiation of at least one specifiable wavelength range. For this purpose, a reflecting metal layer is applied, for example. The semiconductor laser having a laser layer is able to be fastened to a carrier element with the aid of a solder layer.

Abstract: A laser ignition device for an internal combustion engine, in particular of a motor vehicle, having a laser device for generating laser pulses, and having a pumped light source for optically pumping the laser device. A photodiode system is situated in the area of an optical connection between the pumped light source and the laser device in such a way that pumped radiation generated by the pumped light source and the laser radiation generated by the laser device may each be irradiated at least partially onto a photodiode of the photodiode system.
