Abstract
A novel method is reported for stabilising an actively modelocked Er-doped fibre laser by controlling its cavity length to suppress the relaxation oscillation RF power of the laser output. This RF power is a good measure of laser instability. With this method, the RF power ratio between modelocking frequency and background noise is kept to more than 70 dB, and stable bit-error-free operation at 6.3 GHz is realised for over 6 h.Keywords
