Abstract
A simple technique, based on a double optoelectronic feedback loop, is proposed and demonstrated to suppress intensity noise in high bit rate pulse trains generated by a frequency-modulated Er-Yb:glass laser. Relaxation oscillation and frequency detuning noise components are reduced by 18.3 and 33 dB, respectively, achieving residual amplitude fluctuations of <0.9%
