摘要：

We show analytically and numerically that the application, during the storage time, of an additional weak field connecting the lower levels (LLs) of a Lambda system can modify the spin coherence and the amplitude of the retrieved probe without causing distortion. The LL coupling field adds an additional phase-dependent term to the probe propagation equation. The retrieved probe is amplified when the total relative phase Phi=0 or pi and decreased when Phi = pi/2. (C) 2009 Optical Society of America
