Measurements of the Hyperpolarizability Tensor By Means of Hyper-Rayleigh Scattering

Hydrogen bond dynamics in water studied by depolarized Rayleigh scattering

2014 We measured the depolarized Rayleigh light scattering by water from 80°C down to 17°C. The spectra obtained could be analysed into two lines, a broad and a sharp one. From the sharp line we deduced a relaxation time which can be interpreted as a reorientational time due to rotations. The broad line gives a relaxation time which is Arrhenius temperature dependent, with an activation energy ...

Hyper-Rayleigh scattering spectrum of liquid nitromethane.

The vertical vertical (VV), horizontal vertical (HV), and vertical horizontal (VH) hyper-Rayleigh scattering (HRS) spectra were measured for liquid CH3NO2 at T= 300 K. The main HRS spectral component has a width upsilon1=1.28 +/- 0.04 cm(-1), which gives an orientation relaxation time pi=4.1 +/- 0.1 ps in good agreement with other experiments. However, the VH spectrum also contains a previously...

Spectral measurements of hyper-Rayleigh light scattering

An apparatus is described for the measurement of second-order nonlinear optical properties via hyper-Rayleigh scattering with 1 cm spectral resolution of the scattered light. The setup allows a complete investigation of the polarization dependence of the second-harmonic scattered light. The combination of good spectral resolution, polarization analysis, and high sensitivity allows the determina...

Interferometry of hyper-Rayleigh scattering by inhomogeneous thin films.

The use of specific symmetry properties of optical second-harmonic generation (the s, s-exclusion rule) has allowed us to observe high-contrast hyper-Rayleigh interference patterns in completely diffuse light, an effect that has no analog in the case of linear (Rayleigh) scattering.
