Principles and schemes of optical information processing, transmission and storage based on the ultra-short laser impulses' interaction with doped rare-earth ions' crystals are considered. Nonlinear optical effect as a photon echo is discussed. This effect is widely used for the investigation of kinetic processing involving the relaxation of elementary excitations in solids. Possibility of parallel processing of large data arrays in the form of two and three dimensional images and flexibility in controlling data flows are represented. ARchitecture of the various photon echo digital operation, including laser digital vector and matrix-vector multiplication are analyzed. Advantages of optical coherent phenomena for quantum computing are discussed.
