Abstract
In at least one embodiment, the radiation-emitting device comprises a laser bar for emitting laser radiation. The device further includes a waveguide having a core, a cladding, an entry face, and an exit face. The device may include a heat sink having a mounting side where the waveguide is applied thereon, the cladding being arranged at least above and below the core in relation to the mounting side. The device may be configured so that, during operation, the laser radiation impinges on the entry face of the waveguide and passes from there into the core. The core may include a conversion element configured to convert the laser radiation into secondary radiation. The waveguide may be configured to guide the laser radiation and/or the secondary radiation inside the core as far as the exit face by reflection at the interface between the cladding and the core.
