Abstract

We have studied the locking effect of photon-echo responses in a three-level system and the information reproducibility upon coding the information in the temporal shape of the object laser pulse. We have shown that these effects differ from their analogs in the two-level system.

This paper discusses how external spatially inhomogeneous electric fields affect information reproduction in the stimulated-photon-echo response in a three-level system when the information is encoded in the temporal shape of the object pulse and in the time intervals of an echelon of laser pulses taken as the object pulse. The information-locking effect for various encoding schemes is investigated for various unequal spacings of the spectrum of a three-level system.

Optimum conditions for correlation of the temporal shape of an object pulse with a stimulated photon echo response in inhomogeneous external electric fields

Leonid A. Nefediev, É. I. Khakimzyanova, Guzel I. Garnaeva

We have studied the information locking effect and the effect of correlation of the shape of an object laser pulse with the shape of a stimulated photon echo response in the presence of external spatially inhomogeneous electric fields. We have shown that, for the transition 3 H 4 - 3 P 0 in a LaF 3 :Pr 3+ crystal, one can observe the effect of the correlation of the shape of an object laser pulse with the shape of a stimulated photon echo response and, depending on the scheme of the action of external spatially inhomogeneous electric fields, either the information locking effect or the information destroying effect.

How the information-flux density in stimulated photon echo depends on the statistical characteristics of the object laser pulse

А. Р. Сахбиева, L. A. Nefedev, Е. Н. Ахмедшина

This paper discusses how the statistical characteristics of an object laser pulse affect the efficiency with which the information encoded in its temporal shape is reproduced. The dependence of the information-flux density in stimulated photon echo on the area of the object pulse is determined in two-level and three-level systems.

Frequency–time correlation of inhomogeneous broadening in a three-level system and the stimulated photon echo locking effect

L. A. Nefedev, Э. И. Низамова, Guzel I. Garnaeva

The frequency–time correlation of inhomogeneous broadening on different transitions in a threelevel resonant medium in the presence of external spatially nonuniform electric fields is considered. It is shown that, under a certain relationship between the magnitudes of gradients of external nonuniform electric fields acting at different moments of time, it is possible to control the magnitude of the frequency–time correlation on different frequency transitions. An increase in the frequency–time correlation coefficient with certain strengths of external spatially nonuniform electric fields leads to the recovery of the phase memory of the system and an increase in the stimulated photon echo intensity.
