This patent describes a chemical process yielding stimulated emission of visible radiation via fast rear resonant intermolecular energy transfer. It comprises: providing a first source of vapor selected from the group consisting of metal or semimetal vapor; providing a second source of atomic vapor selected from the group consisting of metal or semimetal vapor to serve as receptor atoms to receive the energy; providing a source of reactant to react with the first source of vapor in a highly exothermic reaction which liberates energy exceeding 2.5 eV; chemically reacting the reactant and the first source of vapor to form metastable states of a final reaction product; transferring energy stored in the metastable states of the the reaction product to the second source of atomic vapor serving as receptor atoms by means of near resonant energy transfer; and providing a mirror configuration having first and second mirrors and windows associated with the mirrors.
