Paper Abstract

We report a detailed characterization of the spatial resolution provided by different two-photon absorption spectroscopy techniques used in plasma diagnostics: two-photon absorption laser induced fluorescence (TALIF) and two-photon optogalvanic spectroscopy. Well-understood and characterized spatial resolution has especial importance for a precise control of experimental conditions, and absolute measurements. Beam profiles recorded with high resolution allow calculating the beam propagation and irradiance distribution in the beams overlap, the resulting fluorescence and ionization yield, and the corresponding spatial resolution.
