Spatial and recovery measurements of gain in an electric oxygen- iodine laser

Recent investigations of an Electric Oxygen-Iodine Laser system have shown that computational modeling overpredicts the laser power output measured in experiments for similar gain conditions. To help resolve this discrepancy, detailed 2-axis mapping of gain and gain recovery measurements downstream of an operating laser cavity were performed. Modeling and analyses of the gain recovery experimen...

Ir Radiation Based Optical Emission Method of Singlet Oxygen Concentration Measurement for Chemical Oxygen Iodine Laser and Studying the Effects of Parametric Variations

The chemical oxygen iodine laser (COIL) is the only chemical laser based on the electronic transitions. It emits at 1315 nm on the transition between the spin-orbit levels of the ground state configuration of the iodine atom. Here near resonant energy transfer takes place from a singlet delta oxygen [O 2 (a 1 Δ)] molecule to an atomic iodine atom. The singlet delta oxygen molecules O 2 (a 1 Δ) ...

A MEMS Steam Generator

Previous work [1] has shown that MEMS technology has significant potential to create more compact, higherperforming hardware for chemical oxygen iodine lasers (COIL). In COILs, the laser medium is a flowing gas that must be pumped through the system at high mass flow rates to ensure proper system operation. As a result, compact pumps with high pumping rates are a key element of the COIL system....
