Abstract
A laser light source comprises, in particular, 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, and the filter structure () at least partly attenuates the incoherent second electromagnetic radiation () emitted by the active region along the emission direction ().
