Abstract

The chemical oxygen-iodine laser (COIL) is evaluated now as the most promising chemical laser. Singlet oxygen O2(1Δ) for the COIL is generated in a chemical reaction between gaseous chlorine and basic aqueous hydrogen peroxide. Therefore, oxygen is contaminated by water, hydrogen peroxide vapors, and unutilized chlorine. These molecules do not quench O2(1Δ) practically, but they are effective quenchers for excited iodine atoms.
