Current Status of HF/DF Chain Chemical Laser

Abstract

Experimental performance of the H2 + F2 chain reaction chemical lasers has consistently fallen below the theoretically less advantageous F + H2 cold reaction. This report discusses the current status of chain laser modeling and considers the implications of the computer results. Experimental data have drastically changed the HF(V) V to T,R deactivation rate scale from V to V sup 2.3 independent of the deactivating species. A new H + HF(V) deactivation rate for V greater than or equal to 3 has been measured and determined to be approximately 10 to the 14th power/cc/mole sec. LAMP computer code results with the new kinetic rates have greatly improved the agreement between theory and experiment. The chain reaction for a chemical laser has been determined to be more efficient in the DF-CO2 transfer laser and the HF pulsed laser.
