Abstract: A variable wavelength laser light source to improve the resolution of the outgoing light and output only pure laser light without the natural emitted light has an optical amplification element (laser) 11, a first optical reflector 12 at one end surface 11a of the optical amplification element 11, and a wavelength selection element (diffraction grating) 13 at the other end surface 11b of the optical amplification element 11 which selects and outputs the desired wavelength light emitted by the optical amplification element 11. A second optical reflector 14 receives the outgoing light from the wavelength selection element 13 to form the optical resonator with the first optical reflector 12. A first rotating mechanism 15 rotates the second optical reflector 14 around its axis, and a second rotating mechanism 16 connected to the first rotating mechanism 15 rotates the second optical reflector 14 around a second axis 16a remote from the second optical reflector 14 by rotating the first rotating mechanism.
