Abstract

The second harmonic generation and two-photon luminescence from a colloidal solution of spherical gold nanoparticles at wavelength tuning of exciting radiation is studied in experiments. The measured polarization and spectral characteristics of the second harmonic and two-photon luminescence demonstrate that the observed nonlinear optical response is determined by the dimers that constitute several percent of the total nanoparticle number.
