An actively mode-locked erbium-doped fiber (EDF) laser is constructed that simultaneously emits two wavelengths separated by only 0.7 nm. Temporal-spectral multiplexing of the pulses in the gain medium, rather than careful gain equalization, is used to reduce the effects of gain competition and obtain wavelength stable, room-temperature operation. Analysis of the laser output spectrum shows that temporally spreading the pulses before amplification enables stable multi-wavelength lasing at closely spaced wavelengths.
