Abstract

A simple, grazing discharge along the surface of a dielectric produces copious quantities of ultraviolet radiation in the wavelength range 240-340 nm which can be used to dissociate fluorine molecules. The resultant fluorine atoms begin a chain reaction with D2 which results in the formation of vibrationally excited DR Subsequent lasing occurs on as many as 40 vibration-rotation transitions in the wavelength range 3.8-4.5 µm. If CO2 is added to the gas mixture, rapid v-v transfer from DF* to the CO2 quenches the lasing at 4 µm and results in all of the laser energy appearing at 10.6 µm in the highest gain transitions of the 001-100 manifold.
