Abstract
We study a four-level atomic system with a double-Λ configuration interacting with two probe and two control fields. The linear susceptibilities of the atomic medium show not only the dual electromagnetically induced transparency (EIT) effect, but also an amplification mechanism. The numerical simulations verify that one signal can be amplified in both the transmission and the storage processes, provided two synchronous signals are prepared as input.
