Abstract

The phase-mapping of domain wall kinetics under the uniform steady-state electric field is achieved and investigated in the LiNbO₃ crystals by the digital holographic interferometry. We obtained the sequences of reconstructed three-dimensional and two-dimensional wave-field phase distributions during the electric poling in the congruent and near stoichiometric LiNbO₃ crystals. The phase-mapping of domain wall motions in the two crystals are obtained. Both the phase relaxation and the pinning-depinning mechanism are observed during the domain wall motion. The residual phase distribution is observed after the high-speed domain wall motion. The corresponding analyses and discussions are proposed to explain the phenomena.
