Abstract
In this chapter applications of laser-induced dynamic gratings in real-time holography and phase conjugation are reviewed. The chapter begins with a short introduction to holography and optical computing. Applications of dynamic hologram recording include erasable holographic storage of information, realtime interferometry, real-time recording of optical components such as holographic lenses, prisms etc. and applications in optical signal processing. Nonlinear optical phase conjugation by four-wave mixing in dynamic recording media is discussed. Phase conjugation with cw lasers using photorefractive materials (BaTiO3, KNbO3, ...) and the possibility of self-pumping a phase-conjugate mirror using such materials is described, together with the applications of these mirrors in optical resonators.KeywordsReference BeamWavelength ConversionPhase ConjugationObject WaveRecording MaterialThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
