The optical properties of hot pressed transparent ceramics based on the relaxor ferroelectric (1-x)Pb (Mg1/3, Nb2/3)O3-xPbTiO3 (known as PMN-PT) solid solution system have been examined in the visible region. We report transmission as a function of wavelength, refractive indices as a function of temperature and wavelength, and quadratic electro-optic coefficient data for the 632.8 nm HeNe laser wavelength. For our particular ceramic compositions.93(Pb0.99La0.01)(Mg1/3, Nb2/3)O3-.07PbTiO3 and.90 PMN-.10 PT, the refractive index dispersion is well described by a single term Seilmeier equation. The observed temperature dependence of the refractive indices n(T) can be discussed in terms of polar microregions which alter the refractive indices in these ceramics via the quadratic electro-optic effect. Transverse quadratic electro-optic coefficients measured were in accord with those reported for other Pb containing perovskite oxides.
