Scientific paper

The letter reports on a high-power visible laser operating in the cited transition of HgCl at 5576 A. The first excited state of HgCl was formed directly by chemical reactions in an electron-beam-excited mixture of high-pressure rare gases and small amounts of Hg and CCl4. It is found that a composition of Ar and approximately 10% Xe produced the most intense lasing conditions and that the total laser output from an unoptimized configuration corresponded to a lower-bound laser efficiency of about 0.5%. The dominant formation channel of metastable HgCl under the excitation conditions employed is shown to be rapid three-body recombination of Hg(+) and Cl(-) ions.
