Abstract:
A semiconductor laser device comprising an optically pumped surface emitting vertical emitter which emits in a vertical main radiation direction, and at least one monolithically integrated pump radiation source for optically pumping the vertical emitter, wherein the pump radiation source emits pump radiation in a pump main radiation direction extending transversely with respect to the vertical main radiation direction. In accordance with the invention, suitably dimensioned vertical sections are provided such that modes of the pump radiation are forced completely or at least partly in a vertical direction from this section to reduce absorption losses of the pump radiation at conductive layers.
