Abstract

Optogalvanic signals, caused by laser-excited Rydberg atoms, were measured to estimate the electric field in a DC glow discharge in helium. With a careful analysis of the various factors limiting the detection limit and an experiment to check the analysis, the detection limit of an electric field of 21.5 V/mm was obtained which was limited by the laser spectral width.
