This is only possible for $N=1/8$ squeezed input, and is associated with a pure atomic state, i.e., a completely polarized state. The quadrature for which optimal squeezing occurs depends on the squeezing phase $\\Phi ,$ the Rabi frequency $\\Omega ,$ and the atomic detuning $\\Delta $. Pure states are described for arbitrary $\\Phi ,$ not just $\\Phi =0$ or $\\pi $ as in previous work. For small values of $N,$ there may be a greater degree of squeezing in the output field than the input - i.e., we have squeezing amplification.", "revisions": [ { "version": "v1", "updated": "1998-12-30T16:57:33.000Z" } ], "analyses": { "keywords": [ "pure states", "resonance fluorescence", "driven two-level atom interacting", "amplification", "pure atomic state" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
