    Abstract: A laser light source, comprising a semiconductor layer sequence on a substrate and having an active region and a radiation coupling out area having first and second partial regions and a filter structure. The active region generates coherent first electromagnetic radiation and incoherent second electromagnetic radiation, the coherent first electromagnetic radiation is emitted by the first partial region along an emission direction, the incoherent second electromagnetic radiation is emitted by the first partial region and by the second partial region. The filter structure at least partly attenuates the incoherent second electromagnetic radiation emitted by the active region along the emission direction. The filter structure has at least one filter element arranged on an area of the semiconductor layer sequence which has an extension direction parallel to the emission direction and which is remote from the substrate.

    Abstract: A laser light source, comprising a semiconductor layer sequence having an active region and a radiation coupling out area having first and second partial regions, and a filter structure. The active region generates coherent first electromagnetic radiation and incoherent second electromagnetic radiation. 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 partial region and by the second partial region. The filter structure at least partly attenuates the incoherent second electromagnetic radiation emitted by the active region along the emission direction. The filter structure comprises at least one first filter element disposed downstream of the semiconductor layer sequence in the emission direction and it has at least one layer comprising a material that is non-transparent to electromagnetic radiation.
