An All-fiber Compound Ring Laser and Its Use as a Rotation Sensor

By the theory of syntonic mode selecting in the compound ring in which a narrow band taped fiber filter is embedded and by the uncoupling effect on the bidirectionally operating syntonic mode in the ring of the self provided saturable absorption under the near threshold operation, a bidirectional, simultaneous, single mode operating compact Er doped fiber ring laser with the same frequency is realized, the measurement of rotation sensing of the all fiber ring laser is performed.
