Abstract
An investigation is made on the optical nonlinear characteristics of MgF<sub>2</sub> films containing Cu nanoparticles. When the Cu volume fraction is 0.1, at approximately \varepsilon<sub>m</sub>+ 2\varepsilon<sub>d</sub>= 0, the film exhibits a strong third-order optical nonlinear refractive coefficient of 1.0×10<sup>-9</sup> cm<sup>2</sup>/W, a nonlinear refractive index of about ?4.0×10<sup>-7</sup> esu, a third-order optical nonlinear response of about 6.8×10<sup>-8</sup> esu, and a figure of merit of about 1.0×10<sup>-11</sup>. The result shows that the film may have potential applications in optoelectronic technology.
