Chemical Process Yielding Stimulated Emission Of Visible Radiation Via Fast Near Resonant Energy Transfer

Abstract

A process for increasing the efficiency of a chemical process yielding stimulated emission of visible radiation via fast near resonant intermolecular energy transfer comprising the steps of reacting a first metal vapor with a reactant to form a metastable state of a metal oxide or metal halide and transferring the energy from the metastable state to receptor metal atoms by means of near resonant energy transfer to form electronically excited receptor metal atoms in an inverted configuration by using highly volatile precursor compounds to provide the receptor metal atoms, by introducing a quenchant gas during the energy transfer step, or by introducing CO2 laser photons during the energy transfer step.
