Abstract
Overall HgBr laser efficiencies of ~1% have been achieved in small volume UV preionized discharges of Ne/N2/HgBr2 mixtures with single-pulse energies in the 50-100-mJ range.1 Scaling to larger apertures and pulse energies may be difficult because of strong UV absorption by the HgBr2 reagent. Recently, x rays have been utilized as a means to preionize large-volume rare gas halide discharge lasers.2,3
