Abstract
It is shown that spatial higher-harmonic component of electron-electron attractive interaction brings about condensed excitonic state in nonequilibrium superconductor with quasiparticle injection. Photon emission at the transition of an exciton to Cooper-pair state is possible in the region perturbed by injection. Experiments are shown which seem to support the appearance of excitonic level and the generation of coherent emission of electromagnetic waves in injected superconductor.
