摘要: Abstract We report on the first observation of infrared stimulated emission at wavelengths around 5.8 μm and 3 D 1 Π u →(5) Σ + →(2) (inner) cascade transitions Na 2 . The state is optically pumped with a pulsed XeCl excimer laser (308 nm) or tunable frequency-doubled dye-laser in range 309-289 nm. accompagnied by ultra-violet radiation near 364 Most lines are identified.
