Abstract
Cw laser action in Cd II of natural isotopic abundance has been observed at 5337, 5378, 6355, 6360, 7237, and 7284 Å. Laser oscillation has been achieved with a slotted hollow‐cathode discharge containing He carrier gas at pressures of several Torr. Partial pressures of Cd of the order of 10−2 to 3 × 10−1 Torr were produced by external and/or discharge heating. All transitions are attributed to charge‐transfer collisions between neutral Cd atoms and atomic He ions as the dominant mechanism of excitation.Keywords
