    Abstract
  • Faraday medium was introduced into circular polarized erbium-doped fiber ring laser gyroscope to break the frequency-locked phenomenon. Using Jones matrix, the polarization of Eigen polarization of the laser was proposed. Compared with the laser without Faraday medium, the polarization has not changed. Meanwhile, the parsing expression of the output signal of the gyro was deduced, which indicated that the unlocked fiber ring laser gyroscope can be realized due to the introduction of the Faraday effect.
