Abstract
We demonstrate the possibility to perform space and time resolved measurements of the electric field vector in axisymetric discharges using a laser Stark spectroscopy technique. The method is applied to map out the electric field in discharges through rare gases-potassium vapor mixtures. Such mixtures are chosen because they contain traces of NaK molecules, which is used as a sensitive probe of the electric field. Results are presented concerning the study of DC and transient hollow cathode discharges.
