We report measurements of response time for the intensity-dependent absorption in a single
BaTiO_3 crystal under conditions in which no photorefractive effect can be observed. The …

We report the observation of photorefractive index gratings written and read out in BaTiO_3
using single pulses of 30-psec duration and fluences of 1 to 15 mJ/cm^ 2 at a wavelength of …

Picosecond photoinduced absorption in BaTiO_3 has been observed for the first time to our
knowledge using picosecond laser pulses and a time delay pump–probe technique. The …

Large nonlinear changes of the refractive indices in photorefractive crystals cause various
light-induced scattering processes [1 to 71. In principle all nonlinear scattering nearly …

We present data on the speed of light‐induced refractive index changes in a BaTiO3 single
crystal. The light‐induced erasure rate of a refractive index grating is shown to depend on …

We present experimental data for BaTiO_3 that exhibit an intensity dependence in the
absorption coefficient and the two-beam coupling coefficient at intensities between 0.002 …

The light-induced erasure rate of a photorefractive grating in barium titanate scales
sublinearly with optical intensity over a range spanning 8 orders of magnitude. Additionally …

Electron paramagnetic resonance (EPR) and photo-EPR measurements have been made
on cobalt-doped BaTiO 3 single crystals. Crystals illuminated at 25 K with light in the …

The gain–length product for two-wave mixing in photorefractive BaTiO_3 is calculated as a
function of the angles between a pump beam and a scattered beam and the crystal c axis …
