Paper Abstract

The non-chain reaction HF laser energized by an x-ray photo- triggered discharge has been studied for Ne/SF6/C2H6 and Ne/SF6/H2 gas mixtures. For an active volume of 312 cm3, a high specific output energy of 10 J/l has been reached with an electric efficiency of 4.7% for the mixture with ethane, whereas only 6 J/l is obtained with an efficiency of 3.1% for the mixture with hydrogen. It is shown that discharge instabilities are responsible for the laser emission disruption in the case of the H2-mixture. However, addition of C2H6 to Ne/SF6, in place of H2, induces the discharge stabilization. The higher laser performance obtained with the C2H6-mixture, compared with the performance of the H2-mixture, is a direct consequence of this stabilization effect.
