860 femtoseconds mode-locked fiber laser by Gallium co-doped erbium fiber (Ga-EDF)

Results in Physics, 2019
We proposed and demonstrated a high power mode-locked fiber laser using a new type of gain medium which is called as Erbium Gallium co-doped fiber (Ga-EDF). The mode-locking mechanism is enabled by a graphene-based saturable absorber, which is fabricated

Multiwavelength erbium-doped fiber laser based on a nonlinear amplifying loop mirror assisted by un-pumped EDF

Optics Express, 2012
A multiwavelength erbium-doped fiber (EDF) laser based on a nonlinear amplifying loop mirror (NALM) is proposed and experimentally demonstrated. The NALM provides intensity-dependent transmissivity to equalize different-wavelength powers and the transmission can be uniquely optimized by controlling the cavity loss associated with a section of un-pumped
