Abstract
A method for manufacturing an optically pumped surface-emitting semiconductor laser device, wherein a surface-emitting semiconductor laser layer sequence having a quantum confinement structure is applied onto a common substrate. The surface-emitting semiconductor laser layer sequence outside an intended laser region is removed and a region is exposed. An edge-emitting semiconductor layer sequence is applied onto the exposed region over the common substrate, wherein the exposed region is exposed via the removing step, and the exposed region is suitable for transmitting pump radiation into the quantum confinement structure. A current injection path is then formed in the edge-emitting semiconductor layer sequence.
