Abstract

Non-equilibrium atmospheric pressure plasma jets are the subject of growing interest, due to their applicability in many fields, including material processing, surface treatment and medical applications. However the plasma operates in contact with air, thus species like oxygen and nitrogen diffuse into the plasma. We show a method to characterize an argon jet flowing into open air with active spectroscopy. As plasma source we use a microwave surfatron launcher. Three types of laser scattering are investigated: Rayleigh scattering (scattering on heavy particles), Thomson scattering (scattering on free electrons) and Raman scattering (scattering on molecules). In a plasma with air the Thomson and Raman signals overlap. We separate these contributions with a specially designed fitting method, allowing us to simultaneously measure the electron density, electron temperature, molecular densities and the gas temperature
