    "abstract": "The spontaneous emission is investigated for an effective atomic two-level\nsystem in an intense coherent field with frequency lower than the\nvacuum-induced decay width. As this additional low-frequency field is assumed\nto be intense, multiphoton processes may be induced, which can be seen as\nalternative transition pathways in addition to the simple spontaneous decay.\nThe interplay of the various interfering transition pathways influences the\ndecay dynamics of the two-level system and may be used to slow down the\nspontaneous decay considerably. We derive from first principles an expression\nfor the Hamiltonian including up to three-photon processes. This Hamiltonian is\nthen applied to a quantum mechanical simulation of the decay dynamics of the\ntwo-level system. Finally, we discuss numerical results of this simulation\nbased on a rubidium atom and show that the spontaneous emission in this system\nmay be suppressed substantially.",
