    Abstract: A laser light source for emitting coherent electromagnetic radiation has a vertical far-field radiation profile, having a series of semiconductor layers for generating the coherent electromagnetic radiation. An active region is located on a substrate. The coherent electromagnetic radiation is emitted during operation in an emission direction at least from a main emission region of a radiation output surface and the radiation output surface is formed by a side surface of the sequence of semiconductor layers. A filter element suppresses coherent electromagnetic radiation in the vertical far-field radiation profile. The radiation was generated during operation and emitted by an auxiliary emission region of the radiation output surface. The auxiliary emission region is vertically offset from and spatially separated from the main emission region.
