“…It was shown that in the polarization spectrum the additional narrow resonances arise on the frequencies that satisfy of the conditions of multi -photon resonances. We can explain the result of present researches using results of papers [6,7]. The possibility of Doppler shift compensation is common feature for previous work [7] and present researches.…”

“…Two manifolds shifted on frequency 2kv arise for the case of moving atoms with velocity v. The narrow coherent peaks in the polarization and susceptibility spectrum arise additionally to known dopplerons when all fields are phased (combspectrum and phase control). This work is a prolongation of our previous work [7], where we considered the interaction of two counter propagating waves with two -level system -bi-harmonic (strong modulated) and weak counterpropagated monochromatic field. It was shown that in the polarization spectrum the additional narrow resonances arise on the frequencies that satisfy of the conditions of multi -photon resonances.…”

The method of Doppler-free comb-spectroscopy for dipole transitions was proposed. The numerical calculations for susceptibility spectrum for two-level system driving by strong counter propagating combs were made. The narrow peaks with homogeneous width arise on the background of Doppler counter. The contrast of these peaks is large for largest amplitudes of comb-components. Power broadening is increasing with increasing of field amplitudes. The amplitudes of peaks depend on the phase difference between carrier frequencies of combs. The spectral range of absorption spectrum is determined by the spectral range of comb generator and all homogeneous lines arise simultaneously. The spectral resolution is determined by the width of homogeneously-broadening lines. The physical nature of narrow peaks is in the existing of multi-photon transitions between manifolds of quasi-energy levels arising for different groups of atoms moving with velocities that satisfy to the resonant conditions 2kv= (n+l)Ω⁄j, where n, l, j-are integers and Ω-frequency difference between comb teeth.

“…In order to prove this process we studied a three-level system. The system considered a three-level Λ−type system with a ground state (2). The transition2 ↔ 3 is driven by frequency ω 23 and Rabbi frequency G c .The transition 2 ↔ 1 is driven by frequency ω 21 and Rabbi Frequency g c .…”

“…Distance between control pulses for weak degenerate levels b =0.05, c=0.10, a=0.02(Signals polarized differently) As it has been shown in figure.3 intensity of signal is depends on the delay time exponential. This figure has been gotten by using parameter of distance in equation for detuning probe field [2]. the intensity of echo signal depends on the modulation index of process grating which led to a reduction of the echo signal.Based on [7] during delay time T, spectral diffusion cases frequency grating to earase and their magnitude to decay in time.The results of our simulation are shown in figure.2.…”

“…

The three-level photon echo has been described in different works [1,2] by using rotating wave approximation but none of them didnt get results which show the effects of detuning frequencies on frequency of ground level of system; also the effect distance between two generated levels on signal resonance is being neglected. In this work, we studied a -type system theoretically and numerically.
