Abstract

We present a full quantum mechanical model for a composite-ring erbium-doped fiber laser with a feedback loop, with a view to predict the achievable intensity noise reduction. By adding an electronic feedback term to the noise transfer function of the free running composite-ring fiber laser, an analytical expression is developed for the intensity noise spectrum of the current system. For ring fiber lasers, the model shows that the subcavity can suppress the noise at the high frequency and reduce the cutoff frequency to the quantum noise limit, and the feedback loop has a significant impact on suppressing the intensity noise near the relaxation oscillation.
