Annotation

The spectral diffusion and time-frequency correlation of inhomogeneous (Doppler) broadened line of the gas in the presence of particle collisions with the change of speed was investigated. It was Discussed the impact of spectral diffusion on the formation of response SFE. It was shown that the shift of the resonance frequency of the atoms in the gas varies randomly, resulting in each collision with change of the velocity of the atom. This leads to the uncorrelated of inhomogeneous broadening in a gas at different times and partial loss of phase mem- ory that affects the formation of the photon echo. The result of this is distortion is temporal shape of SPE and re- spectively reproducibility information which is encoded in the temporal shape of object laser pulse.

Keywords
