Paper Abstract

The composite material of gold nanocrystals in porous glass matrix was obtained by chemical deposition. Optical spectra were fitted using Drude model. Real and imaginary parts of third-order nonlinear optical susceptibility were separately measured in surface plasmon resonance area using Z-scan technique and 20 ps 539 nm laser pulses. The obtained values of Reχ(3) was -4.12±0.8×10-8 esu and Imχ(3) was -4.28±0.4×10-7 esu. It was shown that the differences of absorption and refraction nonlinearities from field effect predictions can be satisfactorily explained by local field correction.
