中文摘要	we obtain au and ag nanoparticles precipitated in glasses by irradiation of focused femtosecond pulses, and investigate the nonlinear absorptions of the glasses by using z-scan technique with ns pulses at 532 nm. we observe the saturable absorption behavior for an nanoparticles precipitated glasses and the reverse saturable ones for ag ones. we also obtain, by fitting to the experimental results in the light of the local field effect near and away from the surface plasmon resonance, chi(m)((3)) = 4.5 x 10(-7) and 5.9 x 10(-8) esu for m the imaginary parts of the third-order susceptibilities for au and ag nanoparticles, respectively. the nonlinear response of au nanoparticles in the glass samples arises mainly from the hot-electron contribution and the saturation of the interband transitions near the surface plasmon resonance, whereas that of ag nanoparticles in the glass samples from the interband transitions. these show that the obtained glasses can be used as optoelectronic devices suiting for different demands.
