Highly efficient self-pumped phase conjugation at near-infrared wavelengths by using nominally undoped BaTiO3

By G.W. Ross and R.W. Eason

Abstract

Using a nominally undoped crystal of photorefractive BaTiO3, we have examined self-pumped phase conjugation at near-infrared wavelengths. We report reflectivities as high as 74% between 720 and 800 nm. As expected, the crystal response time increases significantly at longer wavelengths. We believe that this value of reflectivity in the self-pumped geometry is the highest reported to date for this range of wavelengths with the use of a nominally undoped crystal
