Abstract
A wavelength-dependence study of surface second-harmonic generation fr om Si(111) is presented. Femtosecond laser pulses tuned from 430 nm to 710 nm were used to probe the dispersion characteristics of the nonli near response from the surface in the vicinity of bulk absorption. Cha nges in the rotational symmetry and in the phase of the generated seco nd-harmonic signal were observed. An explanation of the observed chang es is given based on a simple anharmonic oscillator model [1].
