Frequency fluctuations of stabilized lasers with anisotropic feedbacks.
A random phase method is proposed to determine the perturbation of the Allan variance of frequency stabilized lasers submitted to optical feedbacks. The role of different feedbacks is quantitatively described for both one-oscillating-eigenstate stabilized lasers and two-oscillating-eigenstate stabilized lasers. The importance of the feedback polarization is isolated in each system. In both cases, the experimental measurements of the Allan variance and of the peak-to-peak frequency variations due to a periodic modulation of the feedback phase are found to be in agreement with the theoretical predictions.
