Title :
Holographic measurements of optically induced refractive index inhomogeneities in bismuth titanate
Abstract :
Optically induced refractive index inhomogeneities (optical damage) in single crystal bismuth titanate (Bi4Ti3O12) have been observed by the method of forming holograms inside the crystal. The maximum index change induced by light at 4880 Å wavelength is approximately 10-5and lasts for a few minutes at room temperature.
