Iron pyrite absorber for ultrashort pulse generation

We demonstrate a passively mode-locked pulse generation in an all-fiber erbium-doped fiber laser (EDFL) ring cavity using an iron pyrite (FeS2) based saturable absorber (SA) for the first time. The laser generates a stable soliton pulse operating at a central wavelength of 1562.4 nm when the 980 nm...
