摘要：

Nonlinear refraction in aqueous colloidal gold at 527 nm was studied using the z-scan technique. While a z-scan with a 35 ns laser showed a large negative lensing, a z-scan with a 4 ps laser showed no measurable refraction. The observed nonlinear refraction is shown to be of thermal origin resulting from energy transfer from gold particles to the water molecules.
