Abstract
High efficiency method of detecting incident photons including illuminating a laser driven gaseous vapor with electromagnetic radiation enabling the excitation of an atom of the vapor upon absorption of an incident photon by the atom, introducing the incident photons into the vapor which is constituted to absorb the incident photons which in response, generates atomic fluroescence to in turn produce a long steam of secondary photons upon the absorption of an incident photon by an atom of the vapor and detecting the long stream of secondary photons with an ordinary low efficiency photo-detector.
