Two-photon absorption laser-induced fluorescence measurement of atomic oxygen density in an atmospheric pressure air plasma jet

摘要

Atomic Oxygen density is measured in an air atmospheric jet system using Two-photon Absorption Laser Induced Fluorescence (TALIF). The TALIF system is calibrated using photolysis of molecular oxygen (O2). The RF power coupled into the plasma is varied and the resulting atomic oxygen density in the plasma plume measured.
