Paper Abstract

For the past several years we have been developing diode laser-based diagnostics for the Chemical Oxygen Iodine Laser (COIL). These systems operate by scanning a tunable diode laser over complete absorption lines in species such as water and oxygen. In this paper we describe measurements of the collisional broadening and shifts of absorption transitions in both water and oxygen. These results have implications for the interpretation of data such as the flow temperature when the diagnostics are used on COIL systems.
