The performance of two-center holographic recording is theoretically studied and described
in detail. We present a systematic method for global optimization of two-center holographic …

The technologically important incorporation of extrinsic defects (Mg 2+, Fe 2+, Fe 3+, Er 3+,
and Nd 3+) in LiNbO 3 is investigated using density-functional theory combined with …

We demonstrate that the interaction of intense femtosecond pulse with photorefractive
crystal at conditions close to the optical-breakdown threshold differs drastically from that of …

Photorefractive optical damage of single beams in LiNbO_3 crystals is analyzed within a
framework of two photoactive centres (Fe^ 2+/Fe^ 3+ and Nb_Li^ 4+/Nb_Li^ 5+). It compares …

Light-induced charge transport in nominally undoped LiNbO 3 crystals essentially differs
from that in Fe-and Cu-doped crystals. Furthermore, it is of relevance for numerous effects …

Femtosecond pump pulses are strongly attenuated in lithium niobate owing to two-photon
absorption; the relevant nonlinear coefficient? _p ranges from? 3.5? cm? GW for? _p= 388 …

We report on the study of photorefractive properties of as-grown nominally pure lithium
niobate and tantalate crystals using whispering gallery mode (WGM) resonators. The …

The appearance of light intensity thresholds for catastrophic optical damage in LiNbO3 is
satisfactorily explained by using a photorefractive model based on the Fe^ 2+? Fe^ 3+ and …

The population decay of light-induced small polarons in iron-doped lithium niobate is
simulated by a Monte-Carlo method on the basis of Holstein's theory. The model considers …

High-intensity single-beam photorefractive data on LiNbO3 show the occurrence of a well-
defined intensity threshold for enhanced deterioration (fanning) of the output beam. That …
