Rayleigh scattering

Applied Optics, 1981
We all know that blue skies and red sunsets are due to the “Rayleigh scattering” of sunlight. But beyond that, Rayleigh scattering means different things to different scientists.

Coherent Rayleigh Scattering

Physical Review Letters, 2000
The spectrum of coherent scattering induced by electrostriction in gases has been analyzed in the previously unexplored, free-molecule limit by solving Boltzmann's equation with a periodic force due to the optical fields. Calculated and measured spectra of several gases at rarefied conditions are nearly Gaussian with widths approximately 10% wider than

HYPER-RAYLEIGH SCATTERING IN SOLUTION

Optics and Photonics News, 1991
The 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

2023
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 ...

Rayleigh Scattering

1999
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.

Coherent Rayleigh-Brillouin Scattering

Physical Review Letters, 2002
Coherent 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 ...

Rayleigh Scattering

2008
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 approximation for axisymmetric scatterers

Optics Letters, 2011
The 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 ...
