As the Mach number increases, the local static temperature gradually approaches the
characteristic gas vibration/dissociation temperature, and significant thermo-chemical …

This Letter reports a femtosecond ultraviolet laser absorption spectroscopy (fs-UV-LAS) for
simultaneous in situ measurements of temperature and species. This fs-UV-LAS technique …

In many low-temperature plasmas (LTPs), the OH radical and temperature represent key
properties of plasma reactivity. However, OH and temperature measurements in weakly …

Manipulating surface charge, electric field, and plasma afterglow in a non-equilibrium
plasma is critical to control plasma-surface interaction for plasma catalysis and …

Nonequilibrium generation of atomic nitrogen and hydrogen governing ammonia production
both in the gas phase and on the catalyst surface is critical to plasma-aided ammonia …

We present the first experimental application of coherent Raman spectroscopy (CRS) on the
ro-vibrational ν2 mode spectrum of methane (CH4). Ultrabroadband femtosecond …

Simultaneous rotational and vibrational temperatures are measured in an N_2 plasma with
rotational coherent anti-Stokes Raman scattering (CARS) resolved with a virtually imaged …
