Two-Wave Mixing and Self-pumped Phase Conjugation withPhotorefractive BaTiO3 at Near-Infrared Wavelengths
-
Abstract
We studied the wavelength dependence of the exponential gain coefficient and response time of the two-wave mixing at near-infrared regime with an undoped BaTiO3. We also report a highly efficient self-pumpkd phase conjugation (SPPC). A 80% SPPC reflectivity at 741 nm was achieved. -
