Abstract:
1. A semiconductor laser device comprising: an optically pumped surface-emitting vertical emitter region which has an active radiation-emitting vertical emitter layer; at least one monolithically integrated pump radiation source for optically pumping the vertical emitter, which has an active radiation-emitting pump layer, wherein the pump layer follows the vertical emitter layer in the vertical direction and a main direction of pump radiation from the monolithically integrated pump radiation source is lateral; a conductive layer provided between the vertical emitter layer and the pump layer, the semiconductor laser device being partially ablated so that the conductive layer is partially exposed; a contact applied on the side of the semiconductor laser device which is closer to the pump layer than to the conductive layer; a further contact applied to exposed areas of the conductive layer; and a layer which is conductive and which is transparent for radiation of a wavelength as generated by the monolithically integrated pump radiation source provided between the conductive layer and the further contact; whereby an electrical field can be applied between the conductive layer and the contact for generating pump radiation by charge carrier injection.
