Abstract

Lasers are commonly used nowadays to investigate the plasma properties (laser-aided plasma diagnostics LAPD). However, in using LAPD, one should always be careful in tuning the laser power density to avoid perturbation of the plasma during the diagnostic. A general formula was given by Kunze [1] to determine the heating of electrons during laser diagnostics via electron-ion inverse bremsstrahlung (IB). In this contribution, it is shown that for low ionization degree and high pressure plasmas, electron-ion IB is a negligible heating process and that electron-atom IB becomes dominant. The criterion for non-invasive LAPD needs then to be revised consequently.
