Abstract
Nonlinear absorption of monolayer graphene suspension is studied in the wavelength of 800 nm using Z-scan method with 50-fs pulses. Nonlinear absorption property of graphene suspension at different excitation intensities is compared. Large reverse saturable absorptions are found and believed to arise from twophoton absorption.
