A laser light source unit for vehicles is provided, having a resonator containing a first end mirror and a second end mirror and an active laser medium in between. The laser light source unit has a pump device for generating a pump radiation into the resonator. The pump radiation is configured such that laser light of the first wavelength, a second wavelength, and/or a third wavelength can be radiated. An intermediate mirror is configured so that the radiation of the second wavelength is reflected, and the radiation of the third wavelength is transmitted. A third end mirror is configured so that the radiation of the second wavelength is reflected. A color control module acts on the radiation of the second wavelength and/or the third wavelength so that an intensity of the stimulated emission of the radiation of the second wavelength is adjusted to the radiation of the third wavelength.
