WebStimulated thermal Rayleigh scattering (R) can be observed in liquids while Stimulated Rayleigh wing scattering (SRWS) is observed in liquids with anisotropic molecules. Additionally, stimulated Rayleigh scattering due to fluctuations of concentration in gas mixtures can also occur. For R the internal mode obeys a diffusion equation.

Rayleigh scattering , named after the 19th-century British physicist Lord Rayleigh (John William Strutt), is the predominantly elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation. For light frequencies well below the resonance … See more In 1869, while attempting to determine whether any contaminants remained in the purified air he used for infrared experiments, John Tyndall discovered that bright light scattering off nanoscopic particulates was … See more The expression above can also be written in terms of individual molecules by expressing the dependence on refractive index in terms of the molecular polarizability α, proportional to the dipole moment induced by the electric field of the light. In this case, … See more The strong wavelength dependence of the scattering (~λ ) means that shorter (blue) wavelengths are scattered more strongly than longer (red) wavelengths. This results in the indirect blue light coming from all regions of the sky. Rayleigh scattering is a good … See more Rayleigh scattering is an important component of the scattering of optical signals in optical fibers. Silica fibers are glasses, disordered materials with microscopic variations of density and refractive index.
