Query: High speed spatially multimode Lambda-type atomic memory with arbitrary
  frequency detuning   We present a general model for an atomic memory using ultra-short pulses of
light, which allows both spatial and temporal multimode storage. The process
involves the storage of a faint quantum light pulse into the spin coherence of
the ground state of Lambda-type 3-level atoms, in the presence of a strong
driving pulse. Our model gives a full description of the evolution of the field
and of the atomic coherence in space and time throughout the writing and the
read-out processes. It is valid for any frequency detuning, from the resonant
case to the Raman case, and allows a detailed optimization of the memory
efficiency.
