Experimental observations of the stepped Cu-atom ionization in the active medium of a Cu laser

Russian Physics Journal Aims and scope

Abstract

An optogalvanic effect in a pulsed copper-vapor laser is discovered and investigated. It is found that the generalized deexcitation rate constant of the resonance level to the ionization state of the active medium is <σv>∼ (3±1)·10−7 cm3·s−1. An optothermal effect caused by the hysteresis of the optogalvanic phenomenon is found experimentally. The feasibility of measuring the stepped ionization constants of resonance and metastable states for a number of metal atoms in a pulse-discharge plasma is discussed.
