Formation of Nano-Scale Domain Structures in Lithium Niobate Using High-Intensity Laser Irradiation

Abstract

The polarization reversal process under pulsed laser irradiation without application of electric field was investigated in single crystalline congruent and MgO doped lithium niobate LiNbO 3 . The nano-domain structures obtained in different experimental conditions were statistically analyzed and characterized in terms of domain growth anisotropy.
