Abstract
It was previosly observed (Aronowitz, 1971; Zarinetchi et al., 1989) that, in a Brillouin fiber-optic laser gyro with identical laser frequencies along the counterpropagating directions, there occur, at low rotation rates, the lock-in phenomena normally encountered in bulk-optic ring laser gyros due to backscattering. This paper presents rotation data that are free from lock-in phenomena, from a laser gyro in which the two Brillouin lasers are separated by a fixed offset at zero rotation rate. Also presented is a measurement of the beat between the two counterpropagating Brillouin lasers, which determines the ultimate performance of this gyro.
