LiNbO 3: Zn single crystals and powders were studied by precise X-ray diffraction methods.
Structural refinement yielded new models of the intrinsic defect structure valid for different Zn …

The paper reviews the results of recent studies of optical-damage-resistant LiNbO3: Me
crystals, with Me standing for Mg, Zn, In, Sc. The effects of Me ions on LiNbO3 are very …

Direct measurements of the bulk photovoltaic current density in photorefractive and crystals
were performed at high light intensities. Illumination of the crystals with light pulses of a Q …

The propagation of high-power femtosecond light pulses in lithium niobate crystals (Li Nb O
3) is investigated experimentally and theoretically in collinear pump-probe transmission …

A new charge-transport model assuming one center in three different valence states is
discussed for explanation of the photorefractive effect. Quantitative description of …

The first edition of the Encyclopedia of Optical and Photonic Engineering provided a
valuable reference concerning devices or systems that generate, transmit, measure, or …

The bending bright spatial optical soliton generation in a photorefractive Fe-doped lithium
niobate (LN: Fe) crystal controlled by pyroelectric effect is demonstrated experimentally. A …

Based on the two-center model and the multi-three-wave mixing model, we theoretically
study the possible origins of the threshold effect of the incident light intensity for the …

The number densities and absorption cross sections of both optically generated and
reduction-induced small electron and hole polarons in LiNbO 3 are determined by means of …

The bulk photovoltaic effect is a long-known but poorly understood phenomenon. Recently,
however, the multiferroic bismuth ferrite has been observed to produce strong photovoltaic …
