Abstract

One of the difficulties of realizing phase conjugation in four-wave mixing (FWM) is the pro duction of intensive phase-conjugate pump waves. This difficulty is eliminated in the phase self-conjugation (PSC) scheme, based on light induced FWM, suggested in Ref. 1. In this scheme (see Fig. 1), a powerful signal wave $E_0\left({\omega }_0\right)\text{exp}i\left({\overrightarrow{k}}_0\overrightarrow{r}-{\omega }_{0}t\right)$ to be conjugated is directed to a resonant-absorbing medium placed in a cavity. As a result of resonance scattering of the signal beam, radiation is induced in the medium; the radiation comprises three spectral components.
