The contribution of intrinsic defects to photoinduced charge transport, i.e. to the photorefraction, is explained. The photorefractive and optical properties of LiNbO3 crystals with different stoichiometry and of those doped with so-called "optical-damage resistant" impurities controlling the intrinsic defect structure are described in detail. Applications are the problem of non-erasable recording of photorefractive holograms in LiNbO3 and the current situation of studies in the ferroelectric switching and domain structure of LiNbO3 as well as the creation of periodically-poled structures for the optical frequency conversion. |

| Publisher Description: Lithium niobate, LiNbO, is an oxide ferroelectric with various kinds of pro- 3 nouncedphysicalproperties. Thisversatilityhaspromoteditscareerinscience anddevices. Ithasbeenparticularlyfruitfulintheopticalregime, wheremany e?ects have been found in LiNbO and devices introduced using it as a host. 3 One of the few big drawbacks, namely the low level laser damage threshold based on photorefraction due to extrinsic defects was discovered very early. A relatively new topic, not involved so far in any general description, is a fundamental dependence of the optical properties of LiNbO on intrinsic de- 3 fects. Their importance has been realised out due to the development of varies growthtechniquesintherecentpast. Theprogressinthegrowthandstudiesof LiNbO crystals with di?erent composition, particularly almost stoichiomet- 3 ric ones, has revealed a signi?cant and sometimes decisive role of the intrinsic defects. For example, the photoinduced charge transport, and therefore the photorefractive properties governing the recording of the phase gratings in LiNbO, are strongly controlled by the content of intrinsic defects. The re- 3 cently found impact of intrinsic defects on the coercive ?eld in LiNbO is 3 of fundamental importance for the creation of periodically poled structures (PPLN) aimed at the optical-frequency conversion in the quasi-phase mat- ing (QPM) mode of operation. As a consequence of these results, an idea of the intrinsic defects in LiNbO has been developed during the last decade 3 and involves microscopic studies on defects, photorefraction and ferroelectric switching using spectroscopic and structure methods. |
