K. Buse, LIGHT-INDUCED CHARGE-TRANSPORT PROCESSES IN PHOTOREFRACTIVE CRYSTALS .2. MATERIALS, Applied physics. B, Lasers and optics, 64(4), 1997, pp. 391-407
The charge transport processes in different photorefractive oxide crys
tals are reviewed and consequences for applications are outlined. - Th
e light-induced charge transport processes in LiNbO3, LiTaO3, BaTiO3,
Ba1-xSrxTiO3 (0 less than or equal to x less than or equal to 1, BST),
Ba1-xCaxTiO3 (0 less than or equal to x less than or equal to 1, BCT)
, KNbO3, KTa1-xNbxO3 (0 less than or equal to x less than or equal to
1, KTN), Sr1-xBaxNb2O6 (0 less than or equal to x less than or equal t
o 1, SBN) and Bi-12(Si,Ti,Ge)O-20 (BSO, BTO, EGO) are discussed. Utili
zing the knowledge on the charge transport processes, consequences for
applications are deduced; improved techniques for nondestructive read
out of holograms with light of the recording wavelength are described.
