Stimulated Brillouin fiber-optic laser gyroscope.
We achieved simultaneous bidirectional lasing in an all-fiber ring laser, using stimulated Brillouin scattering as the gain medium. The Brillouin lasing threshold was 60 microW for a He-Ne pump at 1.15 microm. The operation of this device as a ring-laser gyroscope was demonstrated.
