Paper Abstract

Laser action at 1315 nm on the I(2P1/2) → I(2P3/2) transition of atomic iodine has been obtained by a near resonant energy transfer from O2(a1Δ) produced using a low-pressure electric discharge. In the electric discharge oxygen-iodine laser (ElectricOIL) the discharge production of atomic oxygen, ozone, and other excited species adds significantly higher levels of complexity to the post-discharge kinetics which are not encountered in a classic purely chemical O2 (a1Δ) generation system. In this paper, the discharge species output for laser operating conditions are discussed. Spatial measurements of O2(a1Δ) and O2 (b1Σ) are reported, and various methods for the determination of atomic oxygen levels are discussed and compared. The injection of NOX into the system to benefit O2(a1Δ) production is investigated.
