Заглавие : Inversion in an extended three-level medium produced by adiabatic population transfer

Аннотация: Features of the adiabatic population transfer are studied with the spatial evolution of interacting pulses propagating in an optically dense medium of three-level A-atoms taken into account. A self-consistent analytical solution describing the spatial-temporal dynamics of interacting short pulses under the conditions of adiabatic population transfer is constructed in the adiabatic approximation with consideration for the first nonadiabatic correction. Practically complete inversion on a forbidden transition determined by coherent (adiabatic) population transfer is shown to take place over a length of the medium, which may exceed the absorption length of a weak probing pulse in the absence of control radiation on the adjacent transition by several orders of magnitude.

Ключевые слова (''Своб.индексиров.''): adiabatic population transfer--coherent population trapping--electromagnetically induced transparency--counterintuitive pulse sequence
Аннотация: The features of spatial and temporal evolution of two short laser pulses propagating in three-level medium under conditions of coherent population trapping and adiabatic population transfer is investigated in adiabatic approximation. It is shown that in both cases pulses can penetrate into a medium at a distance considerably exceeding the length of linear absorption of a single weak probe pulse in absence of a coupling pulse at adjacent transition. The difference of spatial and temporal evolution of level populations in processes of coherent population trapping and adiabatic population transfer is demonstrated. Also we show that the concept of dressed-field pulses is consequence of Manley-Raw relation.

Аннотация: The spatial and temporal dynamics of two short pulses propagating in an optically dense medium of resonant three-level Lambda-atoms is investigated numerically and analytically. The maximum coherence for the Raman transition due to coherent population trapping. it is shown that, at the initial stage of propagation, the waveforms of such pulses only slightly change along the length of the medium, which may considerably exceed the length of linear absorption for a single weak pulse. As the length of the absorbing medium increases, the energy of the probe (first) pulse is completely transferred into the second (control) pulse.

Ключевые слова (''Своб.индексиров.''): adiabatic population transfer--electromagnetically induced transparency--counterintuitive pulse sequence
Аннотация: In this work the feature of spatio-temporal evolution of two partially overlapped short pulses of counterintuitive sequence in a medium of three-level absorbing atoms in conditions of adiabatic transfer of population are investigated. The analytic solution is constructed. It is shown, that selective excitation of two-photon resonant state with a near-unity probability is conserved on the length of medium, which is considerably greater than the absorbtion length of a weak probe pulse in the absence of a coupling pulse at the adjacent transition.

Ключевые слова (''Своб.индексиров.''): adiabatic population transfer--coherent population trapping electromagnetically induced transparency--counterintuitive pulse sequence
Аннотация: The spatial and temporal dynamics of tno short laser pulses propagating in absorbing three-level medium under conditions of induced transparency is investigated in adiabatic approximation. We analyse two cases of electromagnetically induced transparency creating - coherent population trapping and adiabatic population transfer. It is shown that in both cases the probe pulse can penetrate into a medium at a distance considerably exceeding the length of linear absorption of a single weak probe pulse in absence of a coupling pulse at adjacent transition. The difference of spatial and temporal evolution of level populations in processes of coherent population trapping and adiabatic population transfer is although demonstrated.

Ключевые слова (''Своб.индексиров.''): electromagnetically-induced transparency--coherent population trapping--atomic coherence--quantum interference--adiabatic following--dressed field pulses
Аннотация: Spatio-temporal dynamics of two short laser pulses propagating in an absorbing medium, which consists of one-and two-photon resonant ii-atoms, is investigated in the adiabatic approximation. We give an analytical solution and compare it with numerical simulations. It is shown that pulses may propagate in a medium, whose thickness is considerably greater than the length of the linear absorption of a single weak probe wave. Finally, full transfer of the probe pulse energy into the coupling pulse takes place. A vector model of the adiabatic interaction of two pulses with three-level atom is proposed.

Аннотация: The effect of fractional stimulated Raman adiabatic passage in an optically dense medium of three-level Lambda atoms is shown to result in the maximum coherence on the Raman transition on a length of the medium that considerably exceeds the length of linear resonant absorption. The general case of unequal oscillator strengths of the adjacent transitions is analyzed. The results are of interest for coherent anti-Stokes Raman spectroscopy with delayed pulses.
