Abstract

We discuss recent progress in the development of sensitive, diode laser based diagnostics for chemical oxygen iodine lasers. These diagnostics have been developed to the point where multiple species, temperature, and velocity in the flow can be determined. This paper focuses on measurement of collisional broadening parameters that are needed to extract the transnational temperature from the flow. We report the temperature dependance of collisional broadening coefficients for the (3,4) hyperfine transition with helium and oxygen bath gases.
