Paper Abstract

Single-beam phase conjugation (self-phase conjugation, or SPC) was observed in the ferroelectric crystal LiNbO3:Fe using CW HeNe laser (wavelength 632 nm power 10-36 mW). Effective "out/in" reflection coefficient of phase conjugation (defined as the ratio the output phase-conjugated beam to the input laser beam measured before optical elements) was about 30%. For some crystals efficient phase conjugation was followed by the simultaneous generation of Fabry-Perot modes. Phase locking of two HeNe lasers and imaging of the amplitude objects with the help of self-phase conjugation was demonstrated. Appearances of additional beams (in transmission and reflection) have some analogy with the predicted behavior of the "negative-index materials".
