The pump light source generates pump light. The optical fiber causes Raman scattering regarding the optical pump light as nonlinear material. The wavelength division multiplexing optical fiber combiner forms intra cavity regarding light of second order stoke frequency shifted wavelength. The light is stoke frequency shifted by Raman scattering of the optical fiber. The another wavelength division multiplexing optical fiber combiner forms intra cavity regarding light of first and third order stoke frequency shifted wavelength. The light is stoke frequency shifted by Raman scattering of the optical fiber. The short period optical fiber bragg grating selects and reflects fourth stoke frequency shifted wavelength of output wavelength in intra cavity. The intra cavity is formed by the wavelength division multiplexing optical fiber combiner. The long period bragg grating causes loss on fifth order stoke frequency shifted wavelength and prevents oscillation. The fifth order is next order of output wavelength of the intra cavity.

The first means is connected between the pump light source and the wavelength division multiplexing optical fiber combiner. The second means reflects pump light emitted from the pump light source and passing light of output wavelength.
