Paper Abstract

Two fiber laser sources, a resonant fiber laser (RFL) and a superfluorescent fiber laser (SFL), have been given initial tests as gyro sources using a medium quality gyro test bed. The RFL reacted strongly to optical feedback from the gyro circuit resulting in very large unstable errors in the gyro output. These were suppressed substantially by an optical isolator which reduced feedback from the gyro, or by a phase modulator within the laser cavity. The SFL was found to be free of errors of this type when operated at output power levels below a threshold level (about 0.5 mw) for self oscillation due to external optical circuit reflections.
