Abstract

We describe how to control the temporal shape of adiabaton using peculiarities of propagation dynamics under coherent population trapping. Temporal compression is demonstrated as a special case of pulse shaping. The general case of unequal oscillator strengths of two optical transitions in an atom is considered.

Vasily G. Arkhipkin, Ivan V. Timofeev, V. P. Timofeev

In the paper we show how can control temporal shape of laser pulses using the phenomenon of a coherent population trapping (CPT). Temporal compression is demonstrated as a special case of pulse tailoring,. In addition, it is discussed manipulating of a temporal shape of retrieved pulse recorded on basis of CPT.

Coherent control of temporal pulse shaping by electromagnetically induced transparency

Roberto Buffa, Stefano Cavalieri, Marco V. Tognetti

We present the coherent control of the temporal shape of laser pulses obtained by exploiting the propagation dynamics of electromagnetically induced transparency. Temporal compression, as a special case of pulse tailoring, is discussed. We envisage applications in nonlinear optics processes and control of pulse shapes in the vacuum ultraviolet spectral region.

Nonlinear wavefront sharpening in the adiabatic population transfer regime

I. E. Mazets, Boris G. Matisov

We examine the propagation of a pair of electromagnetic pulses through a medium in the adiabatic passage regime in the case of unequal oscillator strengths of two optical transitions in an atom. It is shown that light waves propagating in a nonlinear medium under such conditions are not shape-preserving. We demonstrate that a front sharpening occurs in this case.

Spatial evolution of short laser pulses under coherent population trapping

Vasily G. Arkhipkin, Ivan V. Timofeev

The spatial and temporal evolution is studied of two powerful short laser pulses having different wavelengths and interacting with a dense three-level \ensuremath{\Lambda}-type optical medium under coherent population trapping. The general case of unequal oscillator strengths of the transitions is considered. The durations of the probe pulse and the coupling pulse ${T}_{1,2} {(T}_{2}>{T}_{1})$ are assumed to be shorter than any of the relevant atomic relaxation times. We propose analytical and numerical solutions of a self-consistent set of coupled Schr\"odinger equations and reduced wave equations in the adiabatic limit taking account of the first nonadiabatic correction. The adiabaticity criterion is also discussed taking account of pulse propagation. The dynamics of propagation is found to be strongly dependent on the ratio of the transition oscillator strengths. It is shown that the envelopes of the pulses slightly change throughout the medium length in the initial stage of propagation. This distance can be large compared to the one-photon resonant absorption length. Eventually, the probe pulse is completely reemitted into the coupling pulse during propagation. An effect of localization of the atomic coherence was observed similar to the one predicted by Fleischhauer and Lukin [Phys. Rev. Lett. 84, 5094 (2000)].The spatial and temporal evolution is studied of two powerful short laser pulses having different wavelengths and interacting with a dense three-level \ensuremath{\Lambda}-type optical medium under coherent population trapping.

Spatial evolution of short pulses under conditions of coherent population trapping

Vasily G. Arkhipkin, Ivan V. Timofeev

We study the features of spatial and temporal evolution of two powerful short different-wavelength laser pulses interacting with optical dense three-level Lambda-type medium under condition of coherent population trapping for the general case of unequal transition oscillator strengths. The pulses are simultaneously sent into an atom. The durations of probe and coupling pulses $T_{1,2}$ ( $T_2>T_1$ ) are supposed to be shorter than all relaxation times in the medium. We present analytical and numerical solutions of the self-consistent set of coupled Schr\\"{o}dinger equations and reduced wave equations in adiabatic limit with taking into account the first non-adiabatic correction. The adiabaticity criterion with account of pulse propagation is studied. We find that propagation dynamics depends on the relationship between the transition oscillator strengths. It is shown that at the initial stage of propagation the envelopes of the pulses slightly change along the length of the medium. This distance can be large compared to one-photon resonant absorption length of the medium. Also it is possible a regime of complete reemitting of the probe pulse into the coupling one during propagation. A spatial evolution of the atomic Raman coherence is investigated in detail too.We study the features of spatial and temporal evolution of two powerful short different-wavelength laser pulses interacting with optical dense three-level Lambda-type medium under condition of coherent population trapping for the general case of unequal transition oscillator strengths.

Temporal compression of nanosecond laser pulses using coherent control

Roberto Buffa, Stefano Cavalieri, Lorenzo Fini +2 more

We present a study of the temporal compression of nanosecond laser pulses resulting from the coherent control peculiarities of the propagation dynamics in a regime of electromagnetically induced transparency. We describe the general theoretical framework and discuss the crucial conditions required in order to experimentally realize such a temporal compression scheme. A proof-of-concept experimental realization of a scheme of this type in a sample of hot sodium vapors is currently being implemented: we describe in detail the experimental setup designed for this purpose.We present a study of the temporal compression of nanosecond laser pulses resulting from the coherent control peculiarities of the propagation dynamics in a regime of electromagnetically induced transparency.
