Abstract
A chemical process yielding stimulated emission of visible radiation via fast rear resonant intermolecular energy transfer comprising the steps of reacting a first metal or semimetal vapor with a reactant to produce a metastable excited state reaction product and transferring energy stored in the metastable excited state of the reaction product to a second metal or semimetal vapor by means of near resonant energy transfer to form electronically excited receptor atoms in a population inversion relative to a lower level of excitation of the receptor atoms. In the preferred form of the process, the first metal or semimetal vapor is a group IIIA or IVA element. The second metal or semimetal vapor is of a group IIA or IVA element and the reactant is either ozone, nitrogen oxide, nitrogen dioxide or a halide.
