Abstract

An active current control apparatus for a ring laser gyro includes an apparatus for generating a control signal representative of a current value, such as, for example a microprocessor controller. Apparatus for supplying actively controlled current to the anode of the ring laser gyro in response to the control signal is coupled to the control signal so as to provide a constant current in the ring laser gyro beam path.
