摘要：
The Bi1.5Zn1.0Nb1.5O7 (BZN) thin film has been fabricated on MgO (001) substrate by pulsed laser deposition. The nonlinear optical properties of the BZN film were investigated using Z-scan technique at a wavelength of 532 nm with 25 ps pulse duration. The two-photon absorption coefficient and the nonlinear refractive index of the BZN film were obtained to be 4.2 x 10(-6) cm/W and 1.6 x 10(-10) cm(2)/W respectively, which are comparable with those of some representative nonlinear optical materials. The large and fast response optical nonlinearities indicated that the BZN film is a promising candidate for future photonics devices. (C) 2009 Elsevier B.V. All rights reserved.
