Abstract
The invention relates to a laser light source for generating narrow-band laser radiation with high coherence, comprising a laser diode (), which forms an internal resonator (), and an external resonator () coupled to the internal resonator (). The object of the invention is to improve a laser source of the kind such that it generates narrow-band and coherent laser radiation with high output power and at the same time with high long-term stability. Furthermore, the laser light source is to be produced in a cost-effective manner. The object is achieved by the invention in that the laser diode () runs in an operating mode in which multimode laser radiation is generated, comprising a plurality of spectrally neighboring resonance modes () of the external resonator (). The resonance modes are selected by adapting the spectral characteristics of the external () and internal () resonators.
