1 kHz rate measurement of vibrational/rotational nonequilibrium using hybrid femto/picosecond coherent anti-Stokes Raman scattering in plasma

We report simultaneous 1 kHz single-shot measurement of rotational and vibrational temperature of N2 using hybrid femto/picosecond coherent anti-Stokes Raman scattering of the Q branch of N2 in a non-equilibrium DC glow discharge.
