Abstract

Laser action at 1315 nm on the I( 2P 1/2) → 1( 2P 3/2) transition of atomic iodine has been obtained by a near resonant energy transfer from O 2(a 1Δ) 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 O 2(a 1Δ) generation system. In this paper, the discharge species output for laser operating conditions are discussed. Spatial measurements of O 2(a 1Δ) and O 2(b 1∑) are reported, and various methods for the determination of atomic oxygen levels are discussed and compared. The injection of NO x into the system to benefit O 2(a 1Δ) production is investigated.
