Abstract :
The lock-in range of a ring laser gyroscope has been shown to increase with the time Tp spent in a “locked” state. New measurements show a recovery proportional to (t/Tp)-1/2 after the gyro is unlocked. A model based on an absorption grating, formed by small polaron hopping, gives good agreement if diffusion away from grain boundaries is included
