In this study, single crystals of Bi12TiO20 doped with niobium and terbium were grown by Top Seeded Solution Growth technique (TSSG). Samples with good optical quality were obtained and were investigated concerning optical absorption, optical activit

We report on the measurement of the electro-optic or Pockels coefficient of titanosillenite crystals and show that there is no sensible wavelength dispersion, at least in the explored 510–650 nm wavelength range. This result is in close agreement w

The photo-electromotive-force effect in CdTe:Ge is studied. A nontrivial frequency response with two different cutoff frequencies is found in the sample studied when exposed to 1064 nm wavelength. The experimental results reveal that two photorefract

The synthesis of Bi 2 O 3 -Nb 2 O 5 sillenite phase (BNbO) and the solubility of this phase with Bi 1 2 TiO 2 0 was investigated by solid-state reaction synthesis and niobium doped Bi 1 2 TiO 2 0 (BTO:Nb) crystals were grown by the Top Seeded Solutio

International audience; The photo-electromotive force induced by a speckle pattern vibrating with large amplitude in photorefractive CdTe:V and CdTe:Ge is experimentally studied. This technique is shown to be suitable for transversal amplitude vibrat

Photorefractive materials exhibit photoconductive and electro‐optic properties. The first step in the optical recording process in these materials is the building up of a spatial modulation of electric charges via charge carriers excitation from lo

We use photoconductivity and holographic techniques to characterize some material and transport properties in undoped and doped photorefractive sillenite crystals, with particular emphasis on photorefractive Bi12TiO20. We show how different dopants a

We report an accurate mathematical model describing the photo-electromotive-force signal produced by a speckle pattern of light vibrating in the volume of a photorefractive crystal with a large transverse amplitude. Our model shows that, for vibratio
