The influence of light diffraction on the efficiency of the resonant quantum
 memory on the three-level atom ensemble in the lambda configuration

We continue to study the quantum memory protocol for spatially multimode light based on an
atomic ensemble in the Λ-configuration, which was proposed in [1]. We consider the case for
backward retrieval for which the read-out driving pulse propagates in the opposite direction to
the writing pulse. We estimate the storage efficiency and find the influence of light diffraction
on it. We analyze the process of restoring the transverse profile of signal quantum field.
