Stable and Self-Starting Passively Mode-Locked Fiber Laser for 1.06 mu m and 1.55 mu m by Using Graphene Oxide Saturable Absorber

Abstract

Graphene oxide/PVA film is used as saturable absorber for mode locking erbium-doped fiber laser and ytterbium-doped fiber laser. It provides modulation depths of 2.6% and 6% at 1.06 mu m and 1.55 mu m, respectively. Stable mode-locked pulses are obtained for both lasers confirming that graphene oxide is cost- effective for 1.06-mu m and 1.55-mu m pulse generations.
