Abstract

We report a highly efficient self-pumped phase conjugation (SPPC) at near-infrared wavelengths with an undoped BaTiO₃. A 80% SPPC reflectivity at 741 nm was achieved. We made a detailed investigation on the buildup process of the phase-conjugate signal. A possible mechanism for this highly efficient SPPC mirror is also discussed.
