Along with the transition dipole moment, the dephasing-related factor can be presented in the photon echo intensity scaling law: integrated echo intensity reads SPE(τ) ≈ ∫|p (3)|2dt with: P(3)(τ,T,t) ∝ ∫dt'3∫dt'2∫dt'14Σi=1 R i(t'1,t'2,t'3) × E*1(k→1,t1)E→ 2(k→2,t2)E→(k→3, t3) P(3) third-order nonlinear polarization, R i(t1, t2, t3) nonlinear response functions, electric fields Ei.
