Physical Review A

Optimal control of optical pulse propagation in a medium of three-level systems

Abstract

We develop an optimal control technique (OCT) in order to design a secondary optical pulse that can control the propagation of an arbitrary primary optical pulse in a medium consisting of three-level systems. The output primary pulse shape can be manipulated by designing the shape of the secondary pulse. The OCT is shown to be better than the earlier proposed pulse schemes for protecting the magnitude and shape of the primary pulse from reshaping by the medium.

Optimal control of population transfer in an optically dense medium

Ningjun Wang, HERSCHEL A. RABITZ

We apply the optimal control technique (OCT) to design an optical pulse pair that controls the population transfer in a medium of three-level atoms. The absorption and reshaping of the controlling pulses by the medium are taken into account. The efficiency of the population transfer is improved significantly compared with designs that do not incorporate pulse absorption and reshaping.

Optimal control of pulse amplification without inversion

Ningjun Wang, HERSCHEL A. RABITZ

We apply an optimal control technique (OCT) to design a secondary coupling pulse that can control the amplification of a given primary optical pulse in a dense media of coherently prepared three-level \ensuremath{\lambda}-type atoms without population inversion. Effects of pulse absorption, amplification, and reshaping by the medium are incorporated in the OCT. We demonstrate numerically that shape-invariant as well as shape-distorted amplification without population inversion can be achieved by properly designing the shape of the coupling pulse. The maximum amplification obtainable is shown to be dependent on the initial atomic coherence as well as the upper bound of the coupling pulse intensity. The group velocity of the primary pulse can also be controlled by the coupling pulse. \textcopyright{} 1996 The American Physical Society.

Teaching optimal control theory to distill robust pulses even under experimental constraints

Thomas Hornung, Marcus Motzkus, Regina de Vivie‐Riedle

Optimal control theory (OCT) has wide applicability in the quest for seeking optimal laser pulses in coherent control of quantum phenomena. We have revised OCT making it possible to distill robust electric fields realizable via femtosecond pulse-shaping technology. The simple pulse structures offer direct physical insight into the control mechanism and selectively isolate the most stable pathways involving only few frequencies. Moreover, a generalized functional makes a vital extension in including the laser system used in control experiments.

Quantum control of an optically dense atomic medium: Pulse shaping in a V-type three-level system

Nadia Boutabba, Hichem Eleuch

In this paper, we suggest a straight-forward technique to control the atomic population inversion in a three-level dense medium based on the pulse shaping with a phase-jump. A strong stokes field and two weak probe fields excite the atomic medium via the V-type configuration. First, we reveal that the atomic population inversion is accomplished under a shaped pulse. Second, we show that this is significantly improved by including a phase-jump in the pulse profile. Finally, we suggest a typical combined shape and phase in order to control the dynamics of the atomic population inversion.

Propagation of laser pulse in a three-level Λ-type medium

Li Yongfang

By choosing special temporal profiles of laser pulses,propagation equations which govern the propagation of them in a three-level Λ-type medium is simplified.Some explicit expressions of analytical solutions to the propagation equations are obtained.The physical mechanism of spatial and temporal evolution of the two laser pulses is analyzed analytically.It is shown that the shape of a laser pulse can be manipulated by group velocities or boundary conditions of the propagation equations.

Adiabatic Dynamical Control Physics of Dielectric Media

R. Grobe

We summarize recent developments in the area of the coherent propagation of laser pulses through dielectric media.We will show that the principle of dynamical adiabaticity opens new avenues to control the non-perturbative .and resonant interaction between two laser pulses and a three-level medium.Examples include the formation of stable wave forms that can travel through optical dielectric media in a loss-free manner with arbitrary pulse shapes, novel possibilities to store optical information in dielectric media in the form of spatially dependent excitations and techniques to exploit this information to control laser pulse envelopes.
