Intensity-Dependent Optical Nonlinear Absorption and Refraction of Gold Nanorods

  • Au nanorods dispersed in aqueous solution were prepared with the electrochemical method. The absorption spectrum shows two absorption
    peaks corresponding to the perpendicular and transverse surface plasma
    resonance absorption of the nanorods. The third-order optical nonlinear
    properties are investigated by Z-scans. The signs of the nonlinear absorption coefficient and refractive index are reversed as the intensity of incident laser increases, which is due to the shape change of the gold nanoparticles melted by the intense laser pulses.
