Nominally pure and rhodium-doped barium-calcium-titanate crystals of the congruently
melting composition Ba 0.77 Ca 0.23 TiO 3 (BCT) are grown by the Czochralski technique …

Ruthenium can easily be incorporated into Bi12SiO20 (BSO) and an unusually high (1.3
cm− 1) photorefractive gain was measured in the diffusion regime with a krypton laser at …

The role of defects in the photorefractive effect is known in principle: their photoionization in
the brighter regions of a photorefractive crystal, illuminated by an inhomogeneous light …

The properties of a light-induced absorption and two-color recording were investigated in
three kinds of Ru and Fe codoped LiNbO3 crystals with different Fe concentrations. A …

Using electron paramagnetic resonance, optical absorption, and fast spectroscopy of light-
induced absorption changes, it is shown that codoping BaTiO 3: Rh with Na Ba acceptors …

The charge carrier dynamics in the sillenite type crystal Bi 12 SiO 20 (BSO) doped with
ruthenium is studied by monitoring the optical density changes after nanosecond laser pulse …

We demonstrate the advantages of using high levels of rhodium (2000–3200 ppm) to dope
barium titanate for achieving finite absorption coefficients (0.36 cm-1), high two-beam …

We present an experimental study of the self-diffraction in Rh: BaTiO3 and BaTiO3 crystals
for small angle between the interfering laser beams. Much larger diffraction efficiencies and …

We present an experimental investigation of the photorefractive properties of rhodium-doped
barium calcium titanate (BCT) crystals of the congruently melting composition Ba0. 77Ca0 …
