چکیده انگلیسی
We have performed firstly studies of the photoinduced second order susceptibilities in the Au nanoparticles (NP) A, B and C under simultaneous influence of the bicolor 1064Â nm and bicolor laser treatment (1064Â nm 10Â ns pulsed laser with pulse power densities 532Â nm 10Â ns laser treatment and the cw 300Â mW 532Â nm SHG coherent laser beams. We have studied three types of samples possessing irregular and different dense parameters of the Au NP deposited on the ITO substrate. We have found that the maximal bicolor (1064Â nm and 532Â nm) stimulated optical second harmonic generation for the 10Â ns pulse duration was observed for the samples possessing irregular Au NP deposited on the ITO. We have performed studies of the photoinduced second order susceptibilities in the Au NP under simultaneous influence of the bicolor 1064Â nm and bicolor laser treatment (1064Â nm 10Â ns pulsed laser with pulse power densities 532Â nm 10Â ns laser treatment and the cw 300Â mW 532Â nm SHG coherent laser beams). We have found that during the 15-20Â min of the cw treatment there occur the principal changes in the absorption maxima. These maxima indicate on the occurrence of the additional absorption nearby the 308Â nm and 310Â nm and 345Â nm spectral bands. The later are caused by the occurrence of the trapping levels in the border between the ITO substrate and the Au nanoparticles.
