Quantitative analysis for HF production in the product gases of an ekctrically initiated H?:SF6 laser has been pxformcd by aqueous titration. hfeasuremcnts were taken at an HF laser output of approximately one joule per pulse. Gas chromatographic analysis has revealed the presence of SFJ. A likely mechanism to describe the decomposition of SF6 in an electric discharge, and mechanisms to account for Hf: production in the lase: and titrimeter ze given. Based upon totai f3F production in the laser, 7.2% of the chcmicof energy avaiilable from the reaction F + ii2 + HF* + H appears as laser right autput. As the atomic ratio of F to H in the SFe + Hz mix is increased from 3 to 65, the chemical efficiency is increased and the HF production is decreased, suggesting that col!isionnl deactivation of HF* by Hz limits the laser efficiency.
