Copper superradiant emission from pulsed discharges in copper iodide vapor

Abstract

Superradiant copper laser emission at 5106 and 5782 Å is reported from pulsed discharges in copper iodide vapor at temperatures of about 600°C. Dissociation of the iodide, excitation of the copper atom, and resonance trapping of the 3248 Å copper transitions are proposed as the principal inversion mechanisms.
