Abstract
Both coherent Third Harmonic Generation (THG) at the interfaces of a cuvette filled with a nanocrystal suspension and incoherent Second and Third Harmonic Scattering (THS) from the suspension volume have been studied to quantitatively assess the orientation-averaged third-order susceptibility ãÏNPs(3)ã of ZnO. These two complementary experimental approaches are based on different calibration routes with a nanocomposite model and fused-silica as a reference material for THG, and pNa molecules for THS. Similar and consistent absolute values of ãÏNPs(3)ã (above 10â18m2/V2) are derived and discussed according to the particular orientation averaging procedure that holds for each experimental configuration for a 1064â¯nm excitation wavelength.
