Enhanced production of singlet oxygen, O 2 ( a 1 Δ g ), was observed by reaction of O 2 /He discharge effluents on an iodine oxide film surface in a microwave discharge-flow reactor at 320 K. We observed a two-fold increase in the O 2 ( a ) yields o

Mixing and combusting high-enthalpy flows, similar to those encountered in supersonic combusting ramjet engines, were investigated using a shock tunnel to produce the flow in conjunction with nonintrusive optical diagnostics that monitored the perfor

Microelectromechanical systems (MEMS) offer a promising approach for creating compact, efficient chemical oxygen iodine lasers. In this paper we report the demonstration and characterization of a chip-scale, MEMS-based singlet oxygen generator, or mi

Laser action at 1315 nm on the I( 2 P1/2) → I( 2 P3/2) transition of atomic iodine has been obtained by a near resonant energy transfer from O2(a 1 ∆) produced using a low–pressure electric discharge. In the electric discharge oxygen-iodine las

In this paper we discuss experimental results from spectroscopic and kinetic investigations of the reaction sequence starting with NCl3 + H. Through a sequence of abstraction reactions, NCl(a 1 ∆) is produced. We have used sensitive optical emissio

In this paper we discuss several sensitive diagnostics that have specifically developed for application to COIL and other iodine laser concepts such as AGIL and DOIL. We briefly cover the history of some important diagnostics including recently-devel

This paper discusses methods, using non-intrusive diagnostic techniques, to characterize the detailed dynamics of I* gain and O2(a1Δ) yield on a laboratory microwave-discharge flow reactor, for conditions relevant to the electrically driven COIL con

Preliminary measurements of the yield of O2(1Δ) as a function of power absorbed in an RF discharge are presented. The yield is deduced from measurements of gain/absorption using the PSI Iodine Scan diagnostic coupled with a data reduction technique
