Abstract

Experiments and modeling have led to continued enhancements in the Electric Oxygen-Iodine Laser (ElectricOIL) system. This continuous wave (cw) laser operating on the 1315 nm transition of atomic iodine is pumped by the production of O2(a) in a radio-frequency (RF) discharge in an O 2/He/NO gas mixture. New discharge geometries have led to improvements in O2(a) production and efficiency. Studies of electrode gap continue to improve O2(a) production at high pressures. Additionally, measurements of species exiting the discharge and the determination of discharge parameters such as E/N continue to expand 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 O 2(a) has been demonstrated in both the rectangular cross-section and multi-circular tube discharges.
