Abstract :
A multi-wavelength Erbium-doped fiber (EDF) laser based on four-wave-mixing is proposed and experimentally demonstrated. The 5km single mode fiber in the cavity enhances the four-wave-mixing to suppress the homogenous broadening of the erbium-doped fiber and get the stable multi-wavelength comb. The lasing stability is investigated. When the pump power is 300mW the fiber laser has 5-lasing lines and the maximum fluctuation of the output power is about 3.18dB. At the same time, a laser with 110m high nonlinear fiber (HNFL) is demonstrated. When the pump power is 300mW it has 7-lasing lines (above -30dBm) and the maximum fluctuation is 0.18dB.
