It was obtained the value of relaxation time for copper particles – 3 ps, for gold particles – 5 ps. was obtained the value of nonlinear susceptibility for gold island films c(3) = -8 ?10-5 – nanosecond pulsed excitation, c(3) = 1 ?10-7 – femtosecond excitation.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
