Radial dependence of the excitation process in a Hg ion laser

摘要

In a He‐Hg pulsed discharge, the temporal and radial behaviors of the population densities of He* (2 3S1), Hg*(6 3P0), and Hg+(7p 2P3/2) are studied experimentally in connection with the time variation of the field pattern of the laser oscillation at 615.0‐nm line of Hg‐II. The field pattern of the laser oscillation is explained in terms of the radial distribution of the populations of He*(2 3S1) and Hg*(6 3)P0 atoms which take part in the Penning‐like excitation process.
