[0021] The laser light source unit 1 according to the present invention can be used in a lighting device (for example, a headlight) for a vehicle, or used as an interior lighting device in a vehicle, for example. Alternatively, the laser light source unit 1 may also be used in other light sources for other purposes.
[0022] The laser light source unit 1 basically includes a pump device 2 for generating a pump beam 3 and a resonator 4. The resonator 4 has a first end mirror 5 on the side facing the pumping device 2 and a second end mirror 6 on the side facing away from the pumping device 2. An activated laser medium 7 and a birefringent medium 8 are arranged between the first end mirror 5 and the second end mirror 6 of the resonator 4. In this embodiment, the activated laser medium 7 is arranged between the first end mirror 5 and the birefringent medium 8. The birefringent medium 8 is arranged between the activated laser medium 7 and the second end mirror 6.
