Simulation of a slow beat frequency drift in a large laser gyro

The results of a laser gyro beat frequency slow drift simulation are presented. The case of homogeneous deformations applied to the ring cavity of a large laser gyro is analyzed. It is shown that the model of a backscattering field's interference between conservative and dissipative sources demonstrates a good agreement with the experimental results. The controllable turning of the mirror around its axis allows the influence of backscattering effects to be decreased by more than two orders of magnitude.
