Non-resonant laser-driven narrowing of particle velocity distributions
Ashwini Vaishnav, Matthias Rupp, Olivier De Castro +2
Stark acceleration and deceleration based techniques for generating particle ensembles with low velocity spread are useful in many experimental applications. For a given velocity d…
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…
High-energy chirped nanosecond pulsed laser system for particle diagnostics and manipulation
Stefan Karatodorov, Marios Kounalakis, Gabriel Flores Alfaro +5
An upgraded high-energy nanosecond pulsed laser system tailored for optical particle diagnostics and manipulation capable of pulse energies beyond Joule-level is presented. In addi…
