Paper Abstract

Second Harmonic Generation (SHG) a nonlinear optical process sensitive to medium structure deviation from centrosymmetry has been used to investigate the bulk and the surface of an aqueous phase. Using the combination of incoherent SHG, also named Hyper Rayleigh Scattering (HRS), and interface coherent SHG, we have investigated the neat air-water interface. In this paper, we report an analysis where the experimental conditions have been investigated to have the best contrast between the surface and the volume contributions. Our data are described within a simple model allowing us to normalize the surface contribution to the volume one.
