Wavefront reproduction or reversal, observed earlier experimentally and interpreted for stimulated Brillouin scattering, is considered now in the case of stimulated Raman scattering, i.e., for the scattering accompanied by a relatively large frequency shift. A condition is derived for the frequency shift which ensures that the reproduction effect occurs also in stimulated Raman scattering.

A theoretical investigation is made of stimulated scattering of spatially inhomogeneous radiation under saturation conditions. A system of kinetic equations describing the interaction between the pump radiation and Stokes waves, correlated and uncorrelated with the exciting field, is derived and solved. A quantitative criterion is derived for the quality of wavefront reversal in the case of generation of Stokes radiation from the spontaneous noise and also in the case of a "Brillouin" amplifier.

We use an experimental procedure first proposed by Basov et al 1 to measure the fidelity of the optical wavefront reconstruction process of phase conjugation due to degenerate four-wave mixing by photorefraction in a poled single crystal of p-type BaTiC3. A similar procedure was recently used to measure the phase-conjugate fidelity in stimulated Brillouin scattering.2
