Abstract
Using stimulated Rayleigh–Brillouin-gain spectroscopy, we report velocity measurements in an atmospheric-pressure subsonic nitrogen flow with 10% uncertainty. It is shown that the accuracy of the velocity measurements increases with gas pressure, making this spectroscopic technique ideal for measuring velocity and other parameters of high-pressure (>1-atm) atomic or molecular flows.
