Abstract
In this paper, laser scattering is applied to a cold atmospheric-pressure microwave plasma argon jet in direct contact with air. Spatially resolved measurements clearly show the air entrainment in the plasma jet. Consequently, the contributions from Thomson scattering and Raman scattering (N2 and O2) overlap. With a specially designed fitting method, we are able to obtain ne and Te, in spite of the significant Raman contribution.
