Abstract
We have obtained cw laser action from Cu II at 2486, 2506, 2591, and 2599 Å by exciting a neon discharge in a copper hollow cathode. We have observed 7‐mW cw output power just above threshold and the output appears to saturate at 210 mW under quasi‐cw operation. The four ultraviolet laser lines observed originate from the 3d95s (3D) term of Cu II. The quantum efficiency of the 2500‐Å laser transitions approaches 25%. Each of the four Cu II laser transitions has been employed in the past by spectroscopists as a secondary wavelength standard in the ultraviolet.Keywords
