Abstract

We report cw oscillation on five transitions of Cu⁺ in the near infrared in hollow-cathode He-CuI, He-CuBr, and He-CuCl gas discharges. Excitation of the upper laser levels is attributed to thermal-energy charge-transfer reactions between ground-state He ions and neutral Cu atoms following discharge dissociation of the Cu halide molecules to generate free copper in the volume. Operating temperatures are in the range 400-550°C and threshold currents for oscillation compare favorably with the lowest yet reported for sputtering Cu⁺ lasers.
