Abstract

The peculiarities of the photon echo excitation by two non- collinear pulses in optically dense media with extreme inhomogeneous broadening are investigated theoretically and numerically. Non-linear pulse evolution during propagation is taken into account. Red frequency shift of the primary photon echo signal is predicted. The influence of pulse transformation on the echo time delay is analyzed.

Numerical simulation of photon echo process generation in optically dense media

T. V. Smirnova

The structure of software package for simulating processes of echo-responses generation in optically dense medium is investigated. Complete analysis of the mathematical model realizing multipulse long lived photon echo forming in resonant media is presented taking into account a non-linear evolution of radiation and an irreversible relaxation during the whole time of a pulse sequence action.

Photon echoes in optically dense media

Sergey A. Moiseev, Mahmood Sabooni, Ravil V. Urmancheev

The authors derive analytical expressions for secondary echoes formed under the two-pulse excitation of the optically dense media developing McCall-Hahn area theorem for echo effects. They find that a series of self-reviving echo signals with a total area of 2$\ensuremath{\pi}$ or 0$\ensuremath{\pi}$ is excited and propagates deep in the media demonstrating strong non-linear nature of light-matter interaction at small changes of second pulse area. The pulse area approach paves the way for precise coherent spectroscopy, the study of different photon echoes and quantum control of light pulses in the optically dense media.

Multiple photon echo in optically dense media

Multiple photon echo generation process in extended crystals is investigated taking into account both the contribution of irreversible relaxation during whole excitation time and propagation effects caused by the resonant medium influence on the exciting pulse sequence and echo-responses.

Incoherent photon echo in spectroscopy of optically dense impurity media

В. А. Зуйков, Каримуллин Камиль Равкатович, Tatiana G. Mitrofanova +3 more

The possibility of using incoherent photon echo in spectroscopy of optically dense impurity media is considered. A theoretical approach to description of this phenomenon is presented. The experimental data on incoherent photon echo in ruby at liquid-helium temperature, with transport of an excitation pulse through a fiber, are reported. The spectral dependence of the echo intensity is studied. The decay curve for an incoherent echo signal is investigated, and the phase relaxation time is found to be 98 ns.

Evolution of the stimulated photon echo in optically dense media

Oleg Kh Khasanov, T. V. Smirnova

A numerical investigation is reported of the characteristics of the stimulated photon echo (SPE) excited by a sequence of 2 n ( n ≥ 2) paired pulses in an extended medium. The evolution of these pulses during propagation is taken into account. The SPE is shown to have a threshold governed by the total initial area of the excitation pulses. Stable SPE amplification is observed when this total area exceeds the threshold value, which is π. The optimal conditions for the SPE are identical for optically thin and dense media. This is a cumulative effect. The existence of a threshold affects also the cumulative effect: the nature of the dependence of the SPE amplitude on the number of the excitation pulse pairs varies with their total initial area. The cumulative effect is observed also when the pulse areas are no longer small. The linear part of the dependence of the SPE signal on n becomes narrower when the dimensions of a sample are increased, which is a consequence of the nonlinear nature of the evolution of pulse pairs in extended media.
