摘要:

The nonlinear optical responses of laser-ablated Si nanoclusters were measured at &lgr;=532 nm.Re{&khgr;(3)}values as high as−(1.33±0.33)×10−3esu were measured for films that were only 200 nm thick. The response time for this nonlinearity was as short as 3.5±0.5 ns, limited by our laser pulse duration. ©1997 American Institute of Physics.
