Abstract
The possibility of population gratings creation in a three-level resonant medium using a pair of unipolar attosecond pulses that do not overlap in the medium is studied theoretically. It is shown that the results of the approximate solution of the Schrödinger equation agree with the results of the numerical solution of the system of equations for the density matrix of a three-level medium, the parameters of which are close to the parameters of atomic vapors of rubidium.
