Abstract
We have undertaken extensive time-resolved fluorescence and gain measurements in a number of avalanche discharge devices preionized by VUV arcs under a variety of power deposition levels in an effort to determine the best approach toward development of an energetic tunable blue-green laser using the C-A transition of XeF. The effect of the krypton additive, which greatly improved output lasing in electron-beam-pumped systems, as well as the use of NF3 and F2 as halogen donors has been studied. Lasing in the blue-green in present devices is near threshold (a few microjoules) when configured as an oscillator. The essential question is how to develop a system where laser threshold can be reached in a short enough time so that there is still sufficient gain and sufficient time in the discharge to extract reasonable energies.
