A procedure is developed for determining the radial electron density and temperature profiles of a rotationally symmetric plasma. This high‐resolution technique involves measuring the deflection of laser beams incident transverse to the plasma. Diagnosis of a stable atmospheric pressure argon arc with CO₂ and He‐Ne laser beams yields results in good agreement with spectroscopic methods.
