Temperature measurements in spray flames by spontaneous Raman scattering
Optics Letters, 1996Spontaneous Raman scattering was applied for quantitative temperature measurements in turbulent methanol spray flames. Possible interferences from laser-induced breakdown and elastic light scattered from the fuel drops were discriminated against by optoacoustic means. Polycyclic aromatic hydrocarbons were found to be a negligible source of fluorescence

Improved Sensitivity Spontaneous Raman Scattering Multi-Gas Sensor
Conference on Lasers and Electro-Optics/International Quantum Electronics Conference, 2009We report a backward-wave spontaneous-Raman multi-gas sensor employing a hollow-core photonic-bandgap-fiber to contain gasses and increase interaction length. Silica Raman noise and detection speed are reduced using a digital spatial filter and a cladding seal.

Theory of Spontaneous and Coherent Raman Scattering
1998Abstract The universality of the phenomenon, the convenience of the experimental technique and the simplicity of the spectra obtained enable the effect to be used as an experimental aid to the solution of a wide range of problems in physics and chemistry.

Spontaneous Raman Scattering for Gas Phase Diagnostics
MRS Proceedings, 1988AbstractThe use of spontaneous rotational and vibrational Raman scattering for nonperturbing measurements of temperature and gas phase concentrations in combustion and in materials processing is reviewed. Theory of Raman intensities is briefly discussed and examples of Raman scattering from metal halide vapors in high temperature furnaces, laminar ...

Analyzing natural gas by spontaneous Raman scattering spectroscopy
Journal of Optical Technology, 2013The use of multipass optical systems as well as the compression of the gaseous test medium to increase the signal intensity of the spontaneous Raman scattering of light has been experimentally studied. A description of a prototype developed for a natural-gas analyzer based on spontaneous Raman scattering spectroscopy is presented.

Quantum Random Number Generation using Spontaneous Raman Scattering
CLEO: 2014, 2014We generate a quantum random bit-string at 650kb/s by frequency binning spontaneous Raman scattered photons from a highly-nonlinear As2S3 glass detected using superconducting single photon detectors. The bit-sequences pass all the NIST statistical randomness tests.

Spontaneous Raman Scattering by Polaritons. I. General Theory
physica status solidi (b), 1970AbstractA general theory of Raman scattering (RS) by polaritons in anisotropic crystals with an arbitrary number of phonon branches is developed. A classification of possible scattering variants is given for both uniaxial and cubic crystals. Formulas defining the angular dependence of the integral intensity and scattering line shape are obtained.

Theory of near-resonant spontaneous Raman scattering spectra
Journal of Physics B: Atomic and Molecular Physics, 1980A theoretical analysis of the time development of spontaneous Raman scattering lineshapes is presented. Particular attention is paid to transients caused by the sharp turn-on of the laser fields. The author examines the breakdown of lowest order perturbative ideas, the role of induced widths and shifts and of Rabi oscillations in final-state spectra ...
