Abstract

We review our work on a femtosecond erbium-doped all-fiber laser mode-locked with graphene oxide saturable absorber, which can be conveniently obtained from natural graphite by simple oxidation and ultra-sonication process. The laser directly generated 200 fs pulses at a repetition rate of 22.9 MHz. The stable passively Q-switched operation by graphene oxide saturable absorber in the 1 μm ytterbium-, 1.5 μm erbium-, and 2 μm thulium-doped fiber lasers will be demonstrated as well. These results are comparable with those of graphene saturable absorbers and the superiority of easy fabrication and hydrophilic property of graphene oxide will facilitate its potential applications for ultrafast photonics.
