    摘要: A laser light source including a semiconductor layer sequence having an active region and a radiation coupling-out area having a first partial region and a second partial region different than the first partial region, and a filter structure. The active region generates, during operation, coherent first electromagnetic radiation having a first wavelength range and incoherent second electromagnetic radiation having a second wavelength range. The coherent first electromagnetic radiation is emitted by the first partial region along an emission direction, and the incoherent second electromagnetic radiation is emitted by the first and second partial regions. The second wavelength range includes the first wavelength range, and the filter structure at least partly attenuates the incoherent second electromagnetic radiation emitted by the active region along the emission direction.

    摘要: 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.
