Paper Abstract

Specific laser applications in information systems for two important cases-nonlinear digital computing optical systems and coherent information laser systems-are described. Some new results obtained at the S. I. Vavilov State Optical Institute are presented. The state-of-the-art and possible applications of feedback nonlinear optical systems for digital parallel data processing are discussed. New possibilities produced by employing high-quality laser radiation in transverse distributed wide-aperture bistable systems are presented, and the main properties of such systems (spatial hysteresis, diffraction autosolitons, and switching waves) are discussed. A discussion of coherent information laser systems is included. The results obtained with high-performance neodimium-doped lasers are reviewed. The amplification of single-frequency cw laser radiation in a pulsed solid state amplifier is discussed. Finally, some theoretical and experimental results concerning the frequency purity of amplified signals are presented.
