Аннотация
© 2019 Author(s).Colloidal solutions of gold nanoparticles in water were pumped by filamentary 800-nm, 100-fs laser pulses at variable supercritical peak powers and probed by the accompanying ultrashort white-light supercontinuum pulses. Their broadband (UV-near-IR) spectra revealed the localized plasmon resonance blue-shifting, broadening, and intensity reduction vs the incident peak laser power as a result of the increasing concentration of s-band free carriers additionally photoinjected from high-density d-bands.
