Resolving Nonequilibrium Gas Kinetics in Supersonic Neutral Flows with Coherent Rayleigh Brillouin Scattering
Atulya Kumar, Gabriel Alfaro, Marios Kounalakis +2
We present a characterization of high-speed flows in nonequilibrium thermodynamic conditions using single-shot coherent Rayleigh-Brillouin scattering(CRBS). The technique is applie…

Spark-Induced Shockwave Dynamics Revealed via Nonresonant Four-Wave Mixing
Marios Kounalakis, Mikhail N. Shneider, Alexandros Gerakis
We report on the experimental detection of shockwave dynamics produced in a spark discharge, using a nonresonant four-wave mixing optical technique. In particular, we observe the s…
