LIF investigations of O and NO products in air like RF plasma jet

Abstract

Laser induced fluorescence by one (LIF) and two photon (TALIF) excitation has been employed to characterize NO, O species in the expanded stream of N(2)-O(2) air like low pressure plasma jet. The gas, excited in a coaxial RF capacitive discharge at pressure P(1), expands through a de Laval nozzle into a vessel at P(2)=0.25 Ton at expansion ratio P(1)/P(2) of about 35. The multiple expansion compression waves of the jet are traced by laser induced fluorescence of NO and O dissociation products expanding through the nozzle. The quantitative O and NO densities, obtained by in-situ calibration of TALIF and LIF signals are discussed.
