摘要
A multi-wavelength erbium-doped fiber laser （MEDFL） with simple line structure is experimentally demonstrated by using a Sagnac interferometer as a comb filter. It is shown that the multi-wavelength lasing is quite stable at room temperature due to the four-wave mixing （FWM） effect among different laser channels in the dispersion-shifted fiber cooperated in the laser cavity.
