HYPER-RAYLEIGH SCATTERING IN SOLUTION
Optics and Photonics News, 1991The experimental setup for the implementation of a new technique to determine the hyperpolarizability of nonlinear optical molecules in solution is presented. The new technique, hyper-Rayleigh scattering in solution [K. Clays and A. Persoons, Phys. Rev. Lett. 66, 2980 (1991)], has the advantage over the electric-field-induced second-harmonic generation

Rayleigh scattering is an exact, analytical solution to the problem of radiation scattering in the limit of a vanishingly small scattering particle compared to the radiation wavelength. As such, it is valid for gaseous molecules at wavelengths used in planetary atmospheric studies, resulting in a polarized, conservative scattering increasing toward ...

Abstract In this chapter we particularize the general results of Chapters 3 and 4 to the first nontrivial terms in the low frequency expansions known as Rayleigh approximations or Rayleigh terms of both the near and the far fields. Also included are the leading terms in the scattering cross sections.

Rayleigh approximation for axisymmetric scatterers
Optics Letters, 2011The Rayleigh approximation is known to be designed only for small ellipsoidal scatterers. We suggest an approach that allows one to find a simple, often analytical, long-wavelength approximation for nonellipsoidal particles. We apply the approach to axisymmetric scatterers and utilize Chebyshev particles to study the main properties of the obtained ...

Coherent Rayleigh-Brillouin Scattering
Physical Review Letters, 2002Coherent Rayleigh-Brillouin scattering in gases has been studied experimentally for the first time in the kinetic regime and shown to give line shapes that differ significantly from the spontaneous Rayleigh-Brillouin scattering. A kinetic model was developed to obtain an analytic solution of the line shape for monatomic gases, and good agreement with ...

Abstract In this chapter we develop the stochastic dynamical theory of Rayleigh scattering, from the point of view of a random walk model. Physically this is appropriate to forward and backward scattering experiments where the scattering population is effectively constant over the observation period. From a theoretical point of view, the

Rayleigh and hyper-Rayleigh scatterings in solution
Optics & Laser Technology, 2004Abstract A concept of concentration gradient induced by incident radiation which describes the dependence of the Rayleigh ( I ω ) and hyper-Rayleigh ( I 2 ω ) intensities on the power as well as background concentration is proposed. In our previous paper, we have demonstrated the effect of concentration gradient on the first-, second- and third ...

Rayleigh scattering in Sr0.61Ba0.39Nb2O6
Journal of Applied Physics, 1992Rayleigh scattering (λ=488 nm) is observed in single-crystal Sr0.61Ba0.39Nb2O6 (SBN:61). In particular, the scattered intensity is measured as a function of temperature across the ferroelectric–paraelectric phase transition. The results show that the scattered intensity can vary by as much as two orders of magnitude in passing through the transition ...
