Abstract
The third-order nonlinear optical susceptibilities, , of composite films consisting of nanocrystalline Au and ZnO particles were investigated by use of a degenerate four-wave mixing scheme. The maximum value of , measured at a laser wavelength of 532 nm and a pulse duration of 70 ps, was . Also, this value was achieved with small absorption (the surface-plasmon peak was at the 615-nm wavelength). Our composite materials showed no discernible degradation after they were subjected to irradiation for a total of high-intensity pulses (, 70-ps pulse duration at 500 Hz) during 16 h of testing.
