| Abstract: | Working principle and basic structure of fiber laser gyroscope (FLG) are described and analyzed. According to characteristics of components, an optimized design and parameters choice are built on simulating and modeling. This FLG system project is specified with a structure of bidirectional pumping and bidirectional output to ensure the optical reciprocity. Erbium-doped optical fiber and fiber Bragg grating (FBG) are utilized to achieve modes filtering and linewidth compressing of laser. A novel proposal about signal output from polarization beam splitter (PBS) for distinguishing rotation sense is demonstrated. A circuit project about processing signal and calculating angular rate of gyroscope is shown. |
| Keywords: | fiber laser gyroscope resonant cavity Er-doped fiber |
