Plasma Diagnostics

  • Laser induced fluorescence spectroscopy (LIF)
  • Two photon LIF (TALIF)
  • Tunable diode laser absorption spectroscopy (TDLAS)
  • Fast imaging
  • High resolution optical emission spectroscopy

The research in the field of plasma diagnostics is focused on absolute density measurements of active species (OH, O, O3, Arm) in cold plasmas by means of laser spectroscopy. Spectroscopic techniques are also applied to determine electron temperature, electron density, rotational and vibrational temperature in plasma and afterglow.
