Coherent control of atomic excitation under the action of bichromatic laser field in the presence of electric field

Valery Alexandrovich Astapenko

The paper is devoted to the theoretical investigation of the phase control of atomic photo-excitation in discrete energy spectrum under the action of bichromatic laser field with the frequency ratio 1:2 in the presence of stationary electric field. The calculations are made for the case of alkali atoms. It is shown that the phase modulation of the photo-excitation strongly depends upon the electric field strength and the ratio between the intensities of the monochromatic components of the radiation. The optimal range of parameters for the effect observation is determined.The paper is devoted to the theoretical investigation of the phase control of atomic photo-excitation in discrete energy spectrum under the action of bichromatic laser field with the frequency ratio 1:2 in the presence of stationary electric field.

Optical properties of semiconductors under strong pumping in the M-band region and two-photon probing of the biexciton state

P. I. Khadzhi, А.В. Коровай, D. V. Tkachenko

The behavior of the semiconductor dielectric susceptibility under the action of a strong laser pulse in the range of the luminescent M band and two-photon probe of a biexciton level is investigated. It is shown that the pronounced Autler-Towns effect occurs at the two-photon transition. The position of the absorption peaks is essentially determined by the amplitude and frequency of the pump field.

The correlation of inhomogeneous broadening and the efficiency of data locking in optical echo processors

L. A. Nefedev, G. I. Khakimzyanova

The formation of responses of stimulated photon echo and the efficiency of data locking under the action of a spatially inhomogeneous electric field on a resonance medium are analyzed. It is shown that the action of a spatially inhomogeneous electric field on a resonance medium between the first and second excitation laser pulses leads to the reversible destruction of the phase memory of the medium, which manifests itself in a change in the time-frequency correlation of inhomogeneous broadening. The possibility of controlling the efficiency of data locking by varying the gradient of an external nonuniform electric field is considered.The formation of responses of stimulated photon echo and the efficiency of data locking under the action of a spatially inhomogeneous electric field on a resonance medium are analyzed.
