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