Abstract :
A dual wavelength actively modelocked erbium-doped fiber laser was constructed which generated pulses approximately 50 ps long with repetition rate 2.6 GHz at both 1544.1 nm and 1545.7 nm. The laser cavity incorporated a pair of dispersive gratings to produce temporal-spectral multiplexing of the pulses in the gain medium, which was observed to reduce cross-saturation effects.
