Abstract
An anti-Stokes Raman laser which uses a metastable level of bromine is provided. A medium of molecules each of which contains at least one bromine atom is provided. Means are provided for dissociating the bromine atom from the molecules so that a majority of dissociated bromine atoms go into at least one excited metastable state. Means are provided for jumping the bromine atoms in the metastable state with pump photons in order to provide anti-Stokes Raman output photons by transition from the metastable state to a final state. The output photons have energy equal to the pump photon energy plus an energy gain given by the energy difference between the metastable state and the final state.
