Laser Light Source

A laser light source, comprising

• 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 latter, and
• a filter structure,
• wherein
• 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,
• the incoherent second electromagnetic radiation is emitted by the first partial region and by the second partial region,
• the second wavelength range comprises the first wavelength range,
• 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,
• the at least one first filter element has at least one layer comprising a material that is non-transparent to electromagnetic radiation, and
• the non-transparent material is at least partly arranged on the second partial region.
