摘要：We propose a scheme to generate three-m ode-entangled lights by means of the interaction between the four-level atoms and a three-mode cavity. We deduce the master equation of the cavity field and prove the existence of the three-mode entanglement by employing the criterion of positivity of partial transpose. We also discuss the effects of the initial atomic state and of the Rabi frequency of the classical Pumping field on the entanglement and amplification. (C) 2008 Elsevier B.V. All rights reserved
