Abstract : A computer modeling study of pulsed H2+F2 and D2+F2 chemical lasers has been conducted. This work was directed toward understanding the role of kinetic rotational relaxation and vibrational-rotational relaxation mechanisms in HF and DF lasers. This study resulted in very comprehensive computer models that could predict spectral characteristics of pulsed laser performance using kinetics rate equation data and experimental conditions. In addition, experiments were conducted on a flash initiated pulsed H2+F2 laser facility to generate data to compare with the models developed in this study. Models were also developed that demonstrated the performance of pulsed laser driven amplifiers and optical resonance transfer lasers. Finally, simple models were constructed that permit efficient prediction of pulse energy and pulse power. (Author)
