Abstract

We report the fabrication and the nonlinear optical properties of Rh-doped BaTiO<sub>3</sub> thin films. The films were deposited on SrTiO<sub>3</sub> (100) substrates by pulsed-laser deposition. The deposited Rh:BaTiO<sub>3</sub> thin films were single phase and <i>c</i>-axis orientation investigated by x-ray diffraction. The films exhibited large nonlinear optical effects, which were determined using <i>Z</i>-scan technique at a wavelength of 532 nm with a laser duration of 10 ns. The real and imaginary parts of the third-order nonlinear susceptibility χ<sup>(3)</sup> were 5.71 × 10<sup>−7</sup> esu and 9.59 × 10<sup>−8</sup> esu, respectively. The value of Reχ<sup>(3)</sup> of Rh:BaTiO<sub>3</sub> films is much larger than those of several representative nonlinear optical thin films. The results show that Rh:BaTiO<sub>3</sub> thin films have great potential applications for nonlinear optical devices.
