Measurement of first hyperpolarizabilities by hyper‐Rayleigh scattering
TL;DR: In this article, the origin of spurious and irreproducible signals in the measurement of the hyper-Rayleigh scattering (HRS) of solutions is investigated, and a new cell design, coupled with continuous solution filtration through a 20 nm filter, is shown to improve the reproducibility of the measurement to ±5%.
Journal ArticleDOI
Problems Associated with Hyper-Rayleigh Scattering as a Means To Determine the Second-Order Polarizability of Organic Chromophores
TL;DR: In this article, the second-order polarizability of organic chromophores is extracted using hyper-rayleigh scattering, which is a powerful technique to extract the second order polarization.

TL;DR: In this article, a hyper-Rayleigh scattering (HRS) cell was proposed for non-resonant first hyperpolarizability, β, determination. But the potential of this HRS system for nonresonants first hyper-polarization was highlighted via measurement of a dipolar chromophore at 1500 nm.

Effects of Two-Photon Fluorescence and Polymerization on the First Hyperpolarizability of an Azobenzene Dye
TL;DR: In this article, the authors used hyper-Rayleigh scattering (HRS) to investigate the hyperpolarizability of Disperse Red 19 and a polymer in which DisperseRed 19 appears as a side-chain moiety.
