Abstract
We investigate continuous variable entanglement produced by a V-type atom inside a cavity. Under a strong classical driven condition, we derive an effective Hamiltonian by going beyond the secular approximation. In the momentum representation, we provide a pure-state solution of a two-mode field for the effective Hamiltonian. In the presence of cavity losses and atomic relaxation, especially by taking into account spontaneously generated quantum interference between two atomic decay channels, we show that complete quenching of spontaneous emission is possible under appropriate conditions.
