Abstract

We show that the dynamics of photons in a ring laser gyro are adequately represented by the damped Rabi problem, and thus demonstrate a variety of photonic coherence phenomena analogous to those that occur in atoms. We discuss methods to circumvent the deleterious consequences and exploit the advantageous consequences of these effects. Specifically, we discuss the use of short pulses for the elimination of the gyro dead-band, the use of the dead-band locking frequency for the hypersensitive measurement of scattering and absorption, and the incorporation of fast and slow light media into the cavity for the enhancement of the gyro response.
