Abstract
A method of periodically poling LiTaO3 single crystal at room temperature by applying an external pulsed field is proposed. The relationship between the growth of inverted domains and switching current as well as switching time has been studied. The growth of inverted domains can be controlled by the duration of the pulsed field. The domain structure with period Λ≳8 μm has been fabricated in a 0.3-mm-thick plate of LiTaO3 by partial switching.
