Laser Light Source

A laser light source, comprising:

• a semiconductor layer sequence on a substrate, the 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 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,
• the at least one filter element comprises a surface structure comprising a roughening and/or
• at least one layer comprising a non-transparent material.
