Abstract
Terbium gallium garnet is an interesting representative of the family of rare-earth garnets. In these crystal we have observed a photorefractive effect. This effect is probably linked to the light-induced dichroitic and photochromic behavior of this crystal. Using Kramers-Kronig-relations an estimation shows that the light-induced absorption changes can explain the observed refractive index changes. The observation of holographic writing with orthogonally polarized beams may by attribute to orientationally non- equivalent centers, which become anisotropic by the absorption of light after illumination. Yet, the nature of these centers is unclear. Further studies are already under way to clarify this point.
