<Amnon Yariv> and <David M. Pepper> analyzed <phase conjugation> through degenerate <four-wave mixing>. The nonlinear interaction generates a returning <light> field with the opposite spatial <wave phase> variation. Under appropriate propagation conditions, this lets the returning <wavefront> retrace distortions of the incident field. Their 1977 paper treats amplified reflection and a related mode of parametric <oscillation>, connecting a nonlinear material response with both wavefront control and optical amplification.<Amplified reflection, phase conjugation, and oscillation in degenerate four-wave mixing by Amnon Yariv and David M. Pepper>[Abstract: amplified phase-conjugated propagation and parametric oscillation]{ref}
