Abstract

We demonstrate the Kerr-effect induced by the electric field of single-cycle THz pulses in the relaxor ferroelectrics potassium tantalate/niobate KTa_1-xNb_xO₃ (KTN) and K _1-yLi_yTa_1-xNb_xO₃ (KLTN). We find a slow signal decay component with a time constant of 6 ps in KTN with x=1.8% at room temperature, that decreases upon approaching the transition temperature.
