我们提出了在顶部籽晶溶液生长的钛酸钡晶体中由光折变空间电荷电场诱导形成铁电畴光栅的具体证据。这些域光栅不会被光破坏，并且通过施加场，可以被重新转换成光折变光栅，该光折变光栅比产生它们的光折变光栅吸收更多的光，多达入射光束的67%。
We present concrete evidence for the formation of ferroelectric domain gratings induced by photorefractive space‐charge electric fields in top‐seeded solution‐grown barium titanate crystals. These domain gratings are not destroyed by light and, by applying a field, can be reconverted into photorefractive gratings that diffract much more light than the photorefractive gratings that create them, as much as 67% of an incident beam.
