Abstract

We present results for collisional broadening for selected absorption lines in water vapor and atomic iodine relative to diode laser- based diagnostics for chemical oxygen iodine lasers. For water vapor we measured broadening of the 1.3925 µm line by numerous gases including oxygen, water vapor, nitrogen, and helium. Preliminary measurements were also completed on the (3,4) hyperfine line in atomic iodine at 1.3152 µm.
