Abstract:
This study presents a more complete and wider ranging theoretical study of the amplification and lasing possibilities in alkaline atoms that takes advantage of the multiplicity of hyperfine and magnetic sublevels involved in the 39K 4S1/2-4P1/2 transition. Using drive and probe fields of appropriate polarizations and propagation directions, and optically pumped atoms, (n+m) multi-photon resonances involving absorption of n drive photons and simultaneous emission of m probe photons can be generated. Theoretical predictions are in good agreement with experimental findings.
