Zusammenfassung: 
We present the measurements of the refractive indices and the electro-optic coefficients in lithium niobate crystals doped with a small amount of chromium. It is found that the coefficient r(c) has a significant dependence on the Cr concentration, Electrical moments and deformations, created by Cr3+ at non-isovalent replacement of host lattice ions, can be responsible for this effect.
