Paper Abstract

In this paper, we demonstrate a technique for suppressing the intensity noise of the erbium doped fiber lasers. We show that by introducing negative feedback into the system through the use of a self-biased intracavity loss modulator, the relaxation oscillation noise of the fiber laser could be suppressed by as much as 20 dB. To explain the observed noise reduction phenomenon, a simple theory based on teh linearized rate equation has been developed and also been supported by experimental measurements. We also derive a formula for estimating the maximum achievalbe intesity noise suppression ratio.
