Abstract
Using hollow‐cathode excitation techniques, laser oscillation is obtained at eight new transitions in copper‐helium, silver‐helium, and gold‐helium discharges. All the transitions are in the near‐infrared region and a majority of them are excited on a cw basis. Four of the transitions are obtained in Cu II, two in Ag II, and two in Au II. Lower threshold currents are also reported for five previously observed transitions.
