A set of twelve specially doped lithium niobate crystals were grown to test the effect of the
dopant on holographic recording in the crystals via the photorefractive effect. The crystals …

We show that Cu ions doped in (K x Na 1− x) 0.4 (Sr y Ba 1− y) 0.8 Nb 2 O 6 (KNSBN) form
two energy levels in the band gap, which increase the effective charge-combination-center …

We compare the system performances of two holographic recording geometries using iron-
doped lithium niobate: the 90-degree and transmission geometry. We find that transmission …

Photorefractive two-beam-coupling coefficients are measured and compared in thin and
thick cerium-doped strontium barium niobate crystals fabricated from the same boule. For …

Abstract Pb 1− x Ba x Nb 2 O 6 is a material under consideration for electro-optic and
photorefractive applications. Single crystals of Pb 1− x Ba x Nb 2 O 6 have been grown …

Iron-doped tetragonal potassium tantalate-niobate (KTN: Fe) crystals are used as
photorefractive storage media for holographic double-exposure interferometry. Holographic …

Holographic scattering processes in photorefractive KTa1− xNbxO3 (KTN) crystals are
investigated resulting from the simultaneous action of one or two pump beams. Different …

Anomalous diffraction behavior is observed, for the first time to our knowledge, in doped
KNSBN crystals. The space-charge field increases to its maximum value and then gradually …

A series of LiNbO 3: Zr: Fe: Cu single crystals with various Li/Nb ratios ranging from 0.946 to
1.38 were grown in air by the Czochralski method. Both X-ray powder diffraction and …

Photochromic effect of lithium nioabate crystal doubly doped with Fe and Cu (LN: Fe: Cu)
was investigated for 532 nm wavelength illumination with the aim of nonvolatile holographic …
