Abstract
A ring laser gyroscope is described which includes a laser cavity configured to provide an optical laser path for a pair of counter-propagating laser beams, an optical sensor configured to receive a portion of the energy from the counter-propagating laser beams, and a unit configured to receive outputs from the optical sensor. The unit is configured to utilize the output to generate at least a residual path length control signal, a laser intensity monitor signal, and readout signals.
