Explanation of double-peaked intensity noise spectrum of an external-cavity semiconductor laser

We give a quantitative explanation for the intriguing double-peaked structure in the intensity noise spectrum of an external-cavity semiconductor laser. We find strong suppression of the intensity noise due to coupling between the subthreshold modes (FM-locking). The measured power dependence of the...

Description
Summary:We give a quantitative explanation for the intriguing double-peaked structure in the intensity noise spectrum of an external-cavity semiconductor laser. We find strong suppression of the intensity noise due to coupling between the subthreshold modes (FM-locking). The measured power dependence of the shift and broadening of the double-peaked structure allows detailed diagnostic of the laser.
