Transient optically induced non-centrosymmetry in a solution of octupolar molecules
TL;DR: In this paper, the octupolar symmetry of the molecular species and the orienting field tensor is verified by polarization analysis of the induced second-harmonic susceptibility components, and a 510×10−30 esu secondharmonic hyperpolarizability at 1064 nm fundamental wavelength with 13 D transition dipole moment between excited states is inferred.

Accurate determination and modeling of the dispersion of the first hyperpolarizability of an efficient zwitterionic nonlinear optical chromophore by tunable wavelength hyper-Rayleigh scattering
TL;DR: The wavelength-dependent molecular first hyperpolarizability β of the zwitterionic nonlinear optical (NLO) chromophore picolinium quinodimethane (PQDM) is determined by hyper-Rayleigh scattering (HRS) and used to test and improve theoretical β dispersion models.

New advances in molecular engineering for quadratic nonlinear optics
TL;DR: In this article, the nonlinearity/transparency trade-off of polysilane and polyphenyl-containing ligands was investigated in the context of intramolecular charge transfer with limited conjugation.

Gilles Alcaraz,Lisenn Euzenat,Olivier Mongin,Claudine Katan,Isabelle Ledoux,Joseph Zyss,Mireille Blanchard-Desce,Michel Vaultier +7 more
TL;DR: A series of octupolar molecules derived from the boroxine framework were designed and their optical nonlinearities were investigated by performing harmonic light scattering experiments in solution; the molecules were found to combine excellent transparency in the near UV-visible region (λmax======≤ 280 nm) and significant first-order hyperpolarisabilities (up to β(0)======= 56 × 10−30 esu) as discussed by the authors.

Real-Time Monitoring of the Nucleation and Growth of ZnO Nanoparticles Using an Optical Hyper-Rayleigh Scattering Method
TL;DR: In this paper, the authors measured an increase in the particle hyperpolarizability, βZnO, with increasing particle size, which revealed regions of prevalent nucleation, growth, and ripening.

Raman effect of multiple radiation process and its applications in spectroscopy
TL;DR: In this article, it was shown that with a beam intensity of 0.1 MW/sq cm, the vibrational Raman spectrum of molecules or crystals may be obtained by the three-photon process.
