Monolayer graphene as a saturable absorber in a mode-locked laser
Monolayer graphene as a saturable absorber in a mode-locked laser
We demonstrate that the intrinsic properties of monolayer graphene allow it to act as a more effective saturable absorber for mode-locking fiber lasers when compared to multilayer graphene. The absorption of monolayer graphene can be saturated at lower excitation intensity compared to multilayer graphene, graphene with wrinkle-like defects, or functionalized …
