Abstract

The configurations of Erbium-doped fiber laser and comb filter that work stably have been designed. The stable multiwavelength oscillation of erbium-doped fiber laser with wavelength spacing 0.20nm in 1532nm band had been obtained at liquid nitrogen temperature by optimizing length of erbium-doped fiber and loss of cavity. The experimental results show that, the erbium-doped fiber exhibits obviously different inhomogeneous gain broadening in different band.
