Diffraction manipulation by four-wave mixing
Itay Katzir, Amiram Ron, Ofer Firstenberg
We suggest a scheme to manipulate paraxial diffraction by utilizing the dependency of a four-wave mixing process on the relative angle between the light fields. A microscopic model…
Elimination of the Diffraction of Arbitrary Images Imprinted on Slow Light
O. Firstenberg, M. Shuker, N. Davidson +1
We present a scheme for eliminating the optical diffraction of slow-light in a thermal atomic medium of electromagnetically induced transparency. Nondiffraction is achieved for an…
Ramsey-like measurement of the decoherence rate between Zeeman sub-levels
M. Shuker, O. Firstenberg, Y. Sagi +3
Two-photon processes that involve different sub-levels of the ground state of an atom, are highly sensitive to depopulation and decoherence within the ground state. For example, th…
Theory of Thermal Motion in Electromagnetically Induced Transparency: Diffusion, Doppler, Dicke and Ramsey
O. Firstenberg, M. Shuker, R. Pugatch +3
We present a theoretical model for electromagnetically induced transparency (EIT) in vapor, that incorporates atomic motion and velocity-changing collisions into the dynamics of th…
Storing images in warm atomic vapor
M. Shuker, O. Firstenberg, R. Pugatch +2
Reversible and coherent storage of light in atomic medium is a key-stone of future quantum information applications. In this work, arbitrary two-dimensional images are slowed and s…
Slowing the Decay of an Excited Atom by the Presence of a Detector
D. R. Fredkin, Amiram Ron
The decay of an excited is shown to slow down in the presence of a photo detector. This is similar to the behavior of an atom in a mistuned cavity, and under the conditions of the…
