For the wavelengths within the plasmon band, we have observed saturable absorption and response times of 2.3ps. For the other regions of the spectrum, reverse saturable absorption and lifetimes shorter than 200fs were verified. The nonlinear refractive index is about 2.0 × 10−19m2/W from visible to telecom region, thus presenting an enhancement effect at wavelengths near the plasmon and Cu+2 d-d band.
