Experiments and modelling have led to continued enhancements in the electric oxygen-iodine laser system. This continuous wave laser operating on the 1315 nm transition of atomic iodine is pumped by the production of O 2(a) in a radio-frequency discharge in an O2/He/NO gas mixture. New discharge geometries have led to improvements in O2(a) production and efficiency. Studies of electrode gap continue to improve O 2(a) production at high pressures, and measurements of species exiting the discharge have expanded the understanding of this system. Some of these improvements have already been applied to the laser system, and other advances will be utilized to continue scaling the system to higher laser powers. Over 1 kW of power stored in O2(a) has been demonstrated in both the rectangular cross-section and multi-circular tube discharges.
