Abstract

In this work, we present a straightforward approach to retrieve gas temperatures directly from the effective lifetime τH of the ps-laser excited species measured with picosecond Two Photon Absorption Laser Induced Fluorescence (ps-TALIF). This approach allows for simultaneous measurements of absolute atom densities and gas temperatures performed in moderate-pressure reactive plasmas using an advanced ps-TALIF diagnostic and has been demonstrated for highly collisional hydrogen microplasmas. Furthermore, this methodology was applied to obtain a 2D distribution of gas temperature and H-atom densities in the downstream region of the microplasma discharge.
