On the origin of internal field in lithium niobate crystals directly observed by digital holography
2005 (English)In: Optics express, ISSN 1094-4087, Vol. 13, no 14, 5416- p.Article in journal (Refereed) Published
We show the defect dependence of the internal field in Lithium Niobate using a full-field interferometric method and demonstrate that it can be directly measured on some clusters of defects embedded in a stoichiometric matrix. Results show that the value of the internal field grows in proximity of defects and vanishes far from them, which addresses the long-standing issue about its origin in Lithium Niobate crystal.
