Highly efficient self-pumped phase conjugation at near-infrared wavelengths by using nominally undoped BaTiO3
Optics Letters, 17, (16), . (doi:10.1364/OL.17.001104).
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.
