Equations (1) and (2) are corrected for the silent echo E1 in Fig. 1(a) , where E1 does not affect final photon echo E2 that is under no population inversion. For this, k D = −k RR and k W = k R = k RR , where k i is a propagation wave vector of each optical pulse i. Then the phase matching conditions for E1 and E2 are, respectively,
