Paper Abstract

We report a dual-wavelength actively mode-locked erbium doped fiber laser constructed using one amplitude modulator as mode locker, two fiber Bragg gratings (FBGs) as wavelength filters and two separate parts of gain mediums in order to minimize gain cross-saturation effects. Dual-wavelength pulses with a wavelength spacing of 0.8nm, 1.6nm, 2.4nm and 3.2nm were simultaneously obtained when the modulation frequency was about 2.5GHz in the experiment, respectively. By adjusting the cavity length of one wavelength with a delay line, the repetition rate of this channel can be changed to as two times as the other channel without changing the modulation frequency.
