title: Three-wave and four-wave forward phase-conjugate imaging in photorefractive bismuth silicon oxide.
abstract: Phase-conjugate images in the forward direction are obtained by a new type of four-wave interaction and by the Heer-Griffin type of three-wave interaction. The nonlinear medium is bismuth silicon oxide in which the interaction is optimized by detuning the input beam(s). Measurements are made for several test objects and interbeam angles.
