The first nonlinear optical nanocomposite based on a fusible glassy matrix and a ferroelectric crystal has been obtained. Lead-borate glasses were used as a matrix, and a single-phase ferroelectric powder KNbSi 2 O 7 served as a filler. The quadratic optical nonlinearity of composites has been studied as a function of the temperature and duration of dissolution of crystals in a glass matrix. The conditions for obtaining transparent nanocomposites generating the second optical harmonic are determined. Tab. 1, ill. 3, bibliography: 14 titles.
