8 October 1998 Transient grating in KNbO3/KTaO3 superlattice

Time-resolved degenerate-four-wave-mixing (DFWM) techniques have been used to characterize the nonlinear optical response of a KNbO3/KTaO3 superlattice grown by pulsed laser deposition on a 1 mm thick, (001)-oriented KTaO3 substrate. With a 30 psec pulsed laser, the difference in the nonlinear optical response between bulk KTaO3 and the superlattice was measured. Results indicate that a significant contribution to the response signal is due to the KNbO3 superlattice. The (chi) (3) value was estimated to have increased by 2 orders of magnitude compared to the bulk crystal.
