Abstract

Single shot coherent Rayleigh-Brillouin scattering (CRBS) is a promising non-resonant, four-wave mixing laser diagnostic technique for the measurement of velocity, temperature and density of a gas flow, in a single laser shot of ∼150 ns duration. CRBS has already been successfully demonstrated to measure the temperature, pressure, bulk and shear viscosity, speed of sound and polarizability of a gas or gas mixture. Here, we present the anticipated lowest theoretical estimates for the measurable gas flow velocities and densities. We expect CRBS to be able to resolve air flow velocities down to 10 − 20 m·s⁻¹ at densities as low as 0.1 Torr.
