Superconductor electro-magnetic radiation device

Claim 1

A radiation device, comprising: a. a superconductor having a conductive point contact element which forms a resonant cavity for maintaining standing waves of radiation therein and has an end conductive surface, b. the length and the width of the point contact resonant cavity each being at least one half the wave length of the radiation to be generated therein, and sufficiently small to permit high density current flow to produce lasing without creating a field to destroy electromagnetic radiation, c. a normal conductor having a conductive surface, d. an intermediate insulative film disposed between and in contact with both conducting surfaces to form a barrier permitting current flow of sufficient density to create a state of population inversion, and to sustain electromagnetic resonance within the resonant cavity e. the outer surface of the point contact element being parallel to its central axis and being treated to diffusely reflect phonons, F. temperature control means surrounding the formed injection junction for maintaining it at a temperature below the transition temperature of the superconductor, g. electrical means connected across the formed injection junction for providing an electron flow across the insulative film and into the point contact element of sufficient current density to create a state of population inversion by overpopulating the uncondensed single-particle energy level, whereby the emission rate for photons is increased to a level above the spontaneous phonon emission level to thereby create radiation from the point contact element.
