摘　　要：We demonstrate a multi-wavelength erbium-doped fiber laser （EDFL） using erbium gain and four-wave mixing （FWM） effect in a piece of erbium-doped fiber （EDF） with high erbium ion concentration. The EDF has a pump absorption rate of 24.6 dB/m at 979 nm and is bi-directionally pumped by 980-nm laser diodes. FWM effect redistributes the energy of different oscillating lines and causes multi-wavelength operation. The laser generates more than 22 lines of optical comb with a line spacing of approximately 0.10 nm at the 1569-nm region using only 1.5-m-long EDF.We demonstrate a multi-wavelength erbium-doped fiber laser （EDFL） using erbium gain and four-wave mixing （FWM） effect in a piece of erbium-doped fiber （EDF） with high erbium ion concentration.
