Abstract
We report significant performance improvement of a mode-locked fiber laser gyroscope. A Fabry–Perot cavity GaAlAs laser diode whose front facet was antireflection coated was used as a gain medium. The rms noise equivalent rotation rate measured with a time-interval counter was improved to . The long-term drift of the gyroscope signal was reduced to after a polarizer was inserted into the laser cavity formed with a polarization-maintaining fiber.
