Paper Abstract

A semiconductor preionised pulsed chemical DF laser is operated using SF6 and D2 as fuels. The technique results in uniform, stable and high energy density discharges and provides output energies and peak powers of 40 mJ and 1.2 MW from 20 cc active volume. Discharge measurements are correlated with the output characteristics of the laser to show that the important excitation parameter is the total charge passed by the discharge. A fluorine production rate coefficient is estimated to be 3.67 x 10-9 cm /s and this is shown to be consistent with a dominant role for fluorine production by ionisation of SF6 in the discharge.
