Abstract:

This report investigated the use of fluorine azide FN3 as both an advanced high energy density propellant and as a fuel for an advanced high energy visible wavelength chemical laser. The proposed laser operates by producing the electronically excited NFa metastable species upon thermal dissociation of FN3 and utilizing subsequent energy transfer reactions to pump the BiFA-X laser transitions near 450 nm. The work was done in four major blocks which include 1 Production of FN3 2 Conversion of FN3 to NFa 3 Excitation of BiFA by NFa 4 Measurement of BiFX. In the course of performing this work knowledge was gained concerning the mechanism of reaction and a number of key kinetic rate constants. Also efficient production of electronically excited species was demonstrated at densities large enough to power a high energy laser system. Finally, the BiFX ground state concentration was found to be consistent with a model based on population by radiative cascade from BiFA and removal by NFa at a near gas kinetic rate. These results support the development of an NFBiF chemical laser that is operable at visable wavelengths. TTL
