摘要：

The electro-optic (EO) properties of a new lead-free ceramic based on a (1 - x)K0.5Na0.5NbO3-xSrTiO(3) solid solution with x = 0.2 have been investigated. This material has a pseudo-cubic perovskite structure and typical relaxor-like properties for x similar to 0.15-0.25 (see Kosec M et al 2004 J. Mater Res. 19 1849-54 and Bobnar V et al 2004 Appl. Phys. Lett. 85 994-6). Measurements of the electric field induced changes in birefringence at room temperature showed a rather large quadratic EO Kerr effect (n(3)R(eff) similar to 1.9 X 10(-16) m(2)V(-2)), with strong dispersion (decrease) in the kilohertz region. Electric field induced second harmonic generation was also observed.
