Study of the Nonlinear Scattering Equation for Au Nanoparticle in Solution

The interaction motion equation between the stimulated light and Au nanoparticle in solution has been transffered into a Langevin equation. The resonance scattering, 2/3 fraction frequency resonanance scattering and 2ω\-0 frequency resorance scattering have been analysed. Some nonlinear scattering phenomena for Au nanoparticle have been explained also by the work.
