Electron-beam-controlled discharge metastable HgCl laser

Laser action of metastable HgCl was observed using an electron-beam-controlled discharge to pump a gas mixture of Hg/Cl2 /Ar. An order of magnitude in the fluorescence enhancement was obtained. This gives an excitation efficiency by controlled discharge about a factor of 2 higher than that by direct...

Description
Summary:Laser action of metastable HgCl was observed using an electron-beam-controlled discharge to pump a gas mixture of Hg/Cl2 /Ar. An order of magnitude in the fluorescence enhancement was obtained. This gives an excitation efficiency by controlled discharge about a factor of 2 higher than that by direct electron-beam pumping. In addition to the previously reported 5576-A laser transition of metastable HgCl, a strong transition at 5584 A was also observed.
