摘要：

The infrared (IR) transmitting nanocrystallized chalcogenide glass only containing alpha-CdGa2S4 IR nonlinear optical crystallites, which were confirmed by x-ray diffraction and Raman scattering measurements, was fabricated through the controllable nucleation and crystallization of the glass with the composition 82GeS(2)center dot 18CdGa(2)S(4) at a temperature of 325 degrees C far below the glass transition temperature (T-g:415 degrees C) for a long duration. A clear second harmonic generation (green light, 532 nm) could be observed in the transparent 82GeS(2)center dot 18CdGa(2)S(4) nanocrystallized chalcogenide glass, demonstrating the IR frequency-doubling function of the prepared nanocrystallized composite material.
