This is accompanied by the creation of a \"coherence wave\" of synchronized molecular oscillations with wavevector {\\Delta}{\\beta} determined by the optical dispersion. Within its lifetime, this coherence wave can be used to shift by {\\Omega}$_R$ the frequency of a third \"mixing\" signal, provided phase-matching is satisfied, i.e., {\\Delta}{\\beta} is matched.
