Abstract

Employing high-yield production of graphene by liquid-phase exfoliation, a series of dispersions with large populations of graphene single and few layers was prepared. Nonlinear optical properties of these graphene dispersions were studied using the open aperture Z-scan technique at 532 nm and 1064 nm. The graphene dispersions exhibit broadband nonlinear scattering induced optical limiting.
