“…EIT is the basis of several applications, such as slow light [2], information transfer between matter and light [3,4], sound wave generation [5], and even a proposed testing of black-hole physics [6]. Several recent reviews [7] elucidated the quantum mechanical mechanism of EIT, which relies on the destructive interference between several pathways which connect the ground and excited states of the atom.…”

Electromagnetic radiation is strongly absorbed by the magnetized plasma if its frequency equals the cyclotron frequency of plasma electrons. It is demonstrated that absorption can be completely canceled in the presence of a second radiation beam, or even a magnetostatic field of an undulator, resulting in plasma transparency at the cyclotron frequency. This effect is reminiscent of the electromagnetically-induced transparency (EIT) of the three-level atomic systems, except that it occurs in a completely classical plasma. Also, because of the complexity of the classical plasma, index of refraction at cyclotron frequency differs from unity. Potential applications of the EIT in plasma include selective plasma heating, electromagnetic control of the index of refraction, and electron/ion acceleration.

“…It is important to emphasise that, contrary to the experiments with EIT [9,10], in DVH the compression factor varies depending on the velocity of the reference signal, though the nonlinear interaction itself may have no influence on the dispersion properties of the information pulse. For example, compression with Ç > 2 can be achieved in a waveguide-type system, where the reference pulse velocity can be made small compared to the group velocity of the information pulse by using different waveguide modes for the two pulses.…”

“…The first one, which was implemented in the experiments with electromagnetically induced transparency (EIT) [9,10], is to let the whole pulse into the medium and then imprint its structure instantaneously on the whole length of the pulse by means of a reference signal coming from one side. In this case, substantial deceleration of the optical pulse is needed if the length of the pulse in vacuum exceeds the length of a given sample of the nonlinear medium (''a holographic plate'').…”

A method of producing holograms of three-dimensional (3D) optical pulses is proposed. It is shown that both the amplitude and the phase profile of 3D optical pulse can be stored in dynamic perturbations of a Raman medium, such as plasma. By employing Raman scattering in a nonlinear medium, information carried by a laser pulse can be captured in the form of a slowly propagating low-frequency wave that persists for a time large compared with the pulse duration. If such a hologram is then probed with a short laser pulse, the information stored in the medium can be retrieved in a second scattered electromagnetic wave. The recording and retrieving processes can conserve robustly the pulse shape, thus enabling the recording and retrieving with fidelity of information stored in optical signals. While storing or reading the pulse structure, the optical information can be processed as an analog or digital signal, which allows simultaneous transformation of 3D continuous images or computing discrete arrays of binary data. By adjusting the phase fronts of the reference pulses, one can also perform focusing, redirecting, and other types of transformation of the output pulses.

“…The light may thus be confined to a cross section about the size of the (resonant) absorption cross section of a single ion which, together with the achievable lengths of these fibres, may compensate for the low concentration, and make slowing and storage of light possible. It would also be possible to set up an optical cavity by writing a Bragg grating in the fibre [38] (or by coating the faces of the crystals in our main proposal) and in this way enhance the interaction of the field with the atomic system, as it has been proposed for free atoms and for ions [39]. An analysis of this proposal lies beyond the purpose of the present paper.…”
