摘要：

采用可分相的Na2O－Al2O3－B2O3－SiO2系为基础玻璃，以CuO／SnO、NaI为原料分别引入Cu＋、I－，成功地制备出CuI激晶掺杂硅酸盐玻璃. 通过X射线粉末衍射（XRD）和高分辨透射电镜（HRTEM）分析观察到玻璃中的晶相和微晶的分布情况；由玻璃的室温透射光谱研究了玻璃的热处理条件与光吸收性的关系. 实验发现，该玻璃对Nd:YAG激光器腔内自由振荡具有脉宽压缩效应.

关键词: CuI微晶掺杂硅酸盐玻璃, 晶相, 透射光谱, 脉宽压缩效应

Abstract:

By selecting phase-separable glass system Na2O-Al2O3-B2O3-SiO2 as the base glass and by introducing Cu+, I- from the starting materials CuO/SnO and NaI respectively, CuI microcrystal doped silicate glasses have been prepared successfully. The microcrystal and its distribution in the glass medium are observed by means of X-ray diffraction and HRTEM. The effects of heating treatment on the optical absorption of glasses is studied by the transmission spectra of glasses at room temperature. It is also found from the experiment that the glasses have the effect of compressing the pulse-width of the free oscillation in the cavity of Nd: YAG laser.
