APPARATUS FOR MINIMIZING THE EFFECTS OF LASER INTENSITY REDUCTION AT COLD TEMPERATURES IN RING LASER GYROS

摘要

A circuit (6, 7, 8, 10, 12, 14) for controlling the run current in a ringlaser gyro (2) includes circuitry for sensing temperature (4), supplying acurrent (16) to the ring laser gyro (2) and controlling the current suppliedto the ring laser gyro (2) and the current varies depending on thetemperature. The current changes at predetermined temperature points.
