Abstract
To provide a light source device for a fiber optic gyroscope capable of broadening the bandwidth of the laser light and improving stability of a scale factor. A light source device for a fiber optic gyroscope configured to drive a fiber optic gyroscope includes: a laser light source, a stabilizing part, and a bandwidth broadening part. The laser light sourceemits a laser light of a predetermined frequency. The stabilizing partstabilizes the predetermined frequency of the laser light emitted from the laser light source. The bandwidth broadening partmakes the laser light stabilized by the stabilizing partinto a light having a continuous broadband spectrum.
