| 摘 要： | A multi-wavelength erbium-doped fiber laser(MEDFL)with simple line structure is experimentally demon- strated 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.
