Investigation of DF Kinetics in the Presence of BF3.

Abstract : Laser modeling calculations have been performed for a helium-free DF laser operating on solid-grain reactants. The laser calculations include deactivation kinetics for BF3 that are based on measurements at 295 K. Reasonable estimates have been made for the scaling of the deactivation rates to higher vibrational levels and for the temperature dependence. The calculations show that the BF3 degrades the laser performance about 4% because of the deactivation kinetics. (Author)
