Paper Abstract

The effects of dispersion and gas flow on the operation of the ring laser gyro are summarized. The theory is shown to predict a dimple in the anomalous dispersion properties of the atomic transition. Experiments were carried out using a 43.4 cm and 21.7 cm visible laser gyro. Scale factor and nullshift results showed consistency and confirmed the existence of the dimple. The peak-peak relative magnitude of the scale factor dimple was found to be approximately 25 x 10-6. Gas flow was varied by unbalancing the discharge currents in the two legs of the laser gyro. A nullshift sensitivity of 0.0066 deg/hr/µamp of unbalance was found. Analysis of the data showed the nullshift sensitivity to velocity flow to be 4.4 deg/hr/cm/sec of velocity unbalance.
