The performance of a stable passive Q-switched Erbium Ytterbium co-doped fiber laser (EYFL) operating at 1532.5 nm is demonstrated using a multi-layer graphene film based saturable absorber. The graphene is synthesized by electrochemical exfoliation of graphite at room temperature in 1% sodium dodec...
