Femtosecond mode-locked 1.5 μm fiber laser based on PEDOT: PSS as saturable absorber

We have successfully demonstrated the soliton mode-locked pulse generation in a 77 m long erbium-doped fiber laser (EDFL) cavity using Poly(3,4-ethylenedioxythiophene): poly (styrenesulfonate) (PEDOT: PSS) as a saturable absorber (SA). The prepared PEDOT:PSS SA film exhibits excellent optical charac...
