Book excerpt: A program to apply diode lasers and ultra-sensitive absorption techniques to a variety of important Air Force problems is described. In this program, new gas phase sensors were developed for several applications including: diagnostics for advanced chemical oxygen iodine lasers (COIL), gas phase sensors for atmospheric studies and environmental monitoring, process manufacturing, and development of control strategies based on outputs from the sensors. In this report we present experimental measurements of collisional broadening coefficients of selected transitions in molecular oxygen and water vapor. We make comparisons to earlier measurements and to models for line broadening. We also discuss the production of optical amplification in molecular iodine pumped by a low power visible wavelength diode laser. Finally we present data from characterizations of diode lasers appropriate for development into sensitive diagnostics for the NCi/I laser system.
