“…It reflects the fact that optical SHG is generally forbidden by symmetry in the dipole approximation for bulk centrosymmetric (randomly oriented) media. Due to the breaking of symmetry on surfaces and in the specificity of nanocrystallites, the appearance of an SHG signal is expected that is usually diffused and depolarized [4] in such media, similarly to the incoherent nonlinear optical scattering in molecular solutions [5]. A crucial role is played here by spatial fluctuations of the medium polarization at doubled frequency.…”

The nonlinear optical properties of gold nanoparticles with different densities of particles on indium–tin oxide (ITO) substrates of different origins are investigated. The coherent photoinduced nonlinear optical effect at 1.32 µm reveals a marked dependence on the interparticle distance and density. The decrease of the interparticle distance with the increase of Au nanoparticle density favours the photoinduced optical second harmonic generation. The maximal second-order optical susceptibility attained at a wavelength of 1.32 µm corresponds to the value of about 4.56 pm V−1. The predominant role of the interface between the Au nanoparticles and the ITO substrate is shown.

Liner and nonlinear-optical properties of oligothiophenes self-assembled monolayers ͑SAM͒ are studied by optical second harmonic interference technique. Linear polarizability and first hyperpolarizability as functions of the number of thiophene rings are calculated using a self-consistent approach for linear and nonlinear optical properties. Both of these dependencies can be described by a power law; a nonzero first hyperpolarizability points to the asymmetry of delocalized electron system that might be due to an adsorption of thiophene molecules on a metal substrate. The influence of a dipole-dipole interaction of molecules arranged in the SAM is discussed.
