The graphical visualized description of quantum dynamics of the resonant three-level L-, V-, L- atomic models is offered. The using of the standard algorithm of the von Neumann reduction causes the disentangling decoherence and the absence of atomic coherence for the n-photon excitation. This result is illustrated by an example of L- atom dynamics. The existence and dynamics of atomic coherence for the n-photon excitation is shown described qualitatively by using the correlated disentangling of composed quantum system (atom + modes of the field) and entering an inoculating quantum coherence in any of subsystems.
