Abstract: (810 Views)
In this research, the optical coefficients of graphene at different concentrations have been measured by the Z-scan technique. First, graphene is produced by electrochemical exfoliation method and then certain concentrations of graphene are prepared in water. The results show that with increasing graphene concentration, the linear absorption coefficient increase and the nonlinear refractive index decrease. These values are of the order (10^(+1))(m^(-1)) and (10^(-7))((cm^2)/w) ,respectively.
