Continuous-wave laser oscillation on transitions of singly ionized iodine has been obtained at increased laser efficiency in helium-iodine gas mixtures using a narrow-bore (3 mm), multiple-anode/hollow-cathode laser tube. The sixteen CW laser lines observed include among their number six which have not formerly been reported as oscillating on a CW basis. Output characteristics of the laser as a function of helium pressure, iodine partial pressure and discharge current have been studied. The output intensity for all lines rises linearly for increasing discharge current beyond threshold to the limit of currents investigated.
