Abstract:
1. A surface emitting inorganic semiconductor laser device, comprising: at least one monolithically integrated pump radiation source having: wherein the contact-connected area comprises at least two strip-shaped contact-connected regions that are disposed at a distance from one another and extend along the emission direction (z); wherein said at least two strip-shaped contact-connected regions are configured for an electrical current to be impressed therethrough and into the active zone; wherein the at least one edge emitting semiconductor structure is configured to emit electromagnetic radiation that has an intensity profile that transversely follows a predeterminable curve with respect to the emission direction (z) of the semiconductor structure; wherein means for inhomogeneous energization of specific regions of an active zone of the semiconductor structure are provided, the inhomogeneity relating to a direction transversely with respect to the emission direction (z) of the semiconductor structure; and wherein means for energization are provided in such a way that the current density in the active zone transversely with respect to the emission direction (z), averaged over the resonator length of the semiconductor structure, follows a predeterminable curve.
