Optical Phase Conjugation Author:M. Gower "Optical Phase Conjugation" provides an introduction to the subject as well as an up-to-date account of the latest developments and applications. The nonlinear optical methods and materials used to obtain phase-conjugate reflectors are discussed in detail by several authors. In particular the processes of degenerate four-wave mixing, stimulated ... more »Brillouin scattering and Brillouin-enhanced four-wave mixing are discussed in depth. The properties and theoretical modelling of photorefractive materials, the most important class of materials used to produce conjugate reflectors, are described at length.« less
