    Abstract: PROBLEM TO BE SOLVED: To emit pulse laser beam in desired wavelength series in a laser light source unit.SOLUTION: A Q switch 55 and a birefringent filter 56 are inserted in an optical resonator including a pair of mirrors 53 and 54 facing each other with a laser rod 51 inserted therebetween. The birefringent filter 56 changes an oscillation wavelength of the optical resonator in association with rotational displacement. A rotation control unit 60 rotates the birefringent filter 56 at a prescribed rotational speed corresponding to the number of wavelengths included in a wavelength series of the pulse laser beam to be emitted. A light emission control unit 61 turns on the Q switch 55 to emit pulse laser beam at the timing that the rotational displacement position of the birefringent filter 56 changes to the position corresponding to the wavelength of the pulse laser beam to be emitted after a flash lamp 52 irradiates the laser rod 51 with exciting light.
