RADIAL DRIFT VELOCITIES IN THE ARGON ION LASER

Abstract
Measured values of the ion radial drift velocity in an argon ion laser discharge tube are presented. The data were obtained from observation of the spontaneous emission line shapes of ion and neutral transitions from the end and from the side of the discharge. The relationship of the data to various postulated excitation processes is considered. The effect of the radial drift velocities on the observed saturation of the axial drift velocities is also discussed.
