چکیده
Xingguo Pan, Mikhail N. Shneider,∗ and Richard B. Miles Department of Mechanical and Aerospace Engineering, Princeton University Princeton, NJ 08540 Abstract We show in this note that, in the CRBS experiment [1], the vibrational modes of the CO2 molecules are frozen. When the gas dynamic parameters are chosen accordingly, the model developed in [1] predicts a line shape that matches with the experimental data. Fitting the theoretical curve to the CRBS data represents a method to measure the speed of high-frequency sound, bulk viscosity, and the rotational relaxation time of molecular gases.

Remote-sensing gas measurements with coherent Rayleigh-Brillouin scattering
We measure the coherent Rayleigh-Brillouin scattering (CRBS) signal integral as a function of the recorded gas pressure in He, Co2, SF6, and air, and we confirm the already established quadratic dependence of the signal on the gas density. We propose the use of CRBS as an effective diagnostic for the remote measurement of gas’ density (pressure) and temperature, as well as polarizability, for g...
متن کاملSpectral narrowing in coherent Rayleigh-Brillouin scattering.
Coherent Rayleigh-Brillouin scattering is a four-wave mixing technique that provides information on various physical properties of the scattering medium in the spectral domain. Being based on density gratings generated by dipole forces, the method requires two pump beams of sufficient spectral width to span the full response bandwidth of the scattering medium. We provide experimental data on th...
متن کاملCoherent Rayleigh-Brillouin Scattering: Influence of the Intermolecular Potential
The spectrum of the coherent Rayleigh-Brillouin scattering (CRBS) of light by a rarefied gas is obtained by solving the Boltzmann equation numerically using the fast spectral method. The influence of the intermolecular potential on the CRBS spectrum is investigated and the accuracy of the prevailing Tenti’s s6 kinetic model is evaluated. Our numerical results show that i) the intermolecular pot...
متن کاملRayleigh-Brillouin scattering of carbon dioxide.
The spectral line shape of spontaneous Rayleigh-Brillouin scattering in CO2 is studied in a range of pressures. The spectrum is influenced by the bulk viscosity η(b), which is a relaxation phenomenon involving the internal degrees of freedom of the molecule. The associated relaxation rates can be compared to the frequency shift of the scattered light, which demands precise measurements of the s...
متن کاملComprehensive Theoretical Study on Threshold Power of Stimulated Brillouin Scattering in Single-Mode Fibers
We have investigated and developed a theoretical approach to explore stimulated Brillouin scattering (SBS) phenomena in single mode fiber. SBS happening threshold power condition has been studied in terms of fiber parameters and input pump power. To assess threshold power precisely, the pump depletion effect and fiber loss has been included by employing 1% criterion. The threshold exponential g...
