Abstract

It is shown that both the spatial and the temporal behavior of a laser pulse can be stored in and recalled from the spatial and spectral distribution of population in the ground state of an inhomogeneously broadened sample. Implications with regard to high-speed frequency-selective optical memories and ultra-high-speed holographic motion pictures are discussed.

Pulse timing and direction in a possible data-storage system. The arrows indicate relative propagation directions. Note that the wave vectors must satisfy the phase-matching condition |kFD| = |k2 + k3k1| = |k3|. The relative directions shown satisfy the phase-matching condition and provide a free-decay signal that is easy to detect since it counterpropagates with respect to the reading pulse. The interval between storage and retrieval is limited only by the stability of the ground-state population distribution. Intervals of the order of years have been predicted in photochemical systems (see Ref. 2). Actual object pulses would be amplitude or freqency modulated to contain data. Since frequency channels are written in parallel, data-transfer rates of roughly Δν1 ≈ 109 Hz can in principle be achieved. (a) If the object pulse (triangular shape at left) is applied before the reference pulse, the free-decay signal (triangular shape at right) mimics the object pulse but is time reversed. (b) If the reference pulse is applied first, the free-decay signal has the same time order as the object pulse.
