Abstract

A surface emitting semiconductor laser device, having at least one monolithically integrated pump radiation source (20), in which the pump radiation source (20) has at least one edge emitting semiconductor structure (9) that is suitable for emission of electromagnetic radiation whose intensity profile transversely with respect to the emission direction (z) of the semiconductor structure follows a predeterminable curve. Such a surface emitting semiconductor laser device emits electromagnetic radiation having a particularly good beam quality.
