Abstract
A study of the absorption saturation characteristics of tetrafluorohydrazine by a 1.5-nsec pulse at 10.6 mu m is presented. A description of the experimental apparatus is provided and the weak-signal absorption of N2F4 is measured with a CW-CO2 laser that can be tuned over many of the CO2 emission lines. The effects of a high-intensity 1.5-nsec pulse are analysed. The saturation of the absorption is studied and the transmission, measured as a function of the pulse-energy density, is presented. A model of the N2F4 molecule is deduced from the experimental results and the rate equations pertaining to this model are developed and solved under the assumption of a rectangularly shaped pulse. Some fundamental constants of N2F4 are then determined by comparing theoretical predictions and experimental results. Truncated
