Wavelength Dependence of the Second-Order Nonlinear Susceptibility of Harmonic Nanoparticles

A tunable wavelength Hyper Rayleigh Scattering setup was developed to assess and compare Second Harmonic Scattering from Lithium Niobate, Zinc Oxide and Bismuth Ferrite nanocrystal suspensions in the 730–1150 nm excitation range.
