To improve the optical storage performance, Sn was doped into Ge_(2)Sb_(2)Te_(5) phase change thin films. The optical and thermal properties of Sn-doped Ge_(2)Sb_(2)Te_(5) film were investigated. The crystal structures of the as-sputtered and the annealed films were identified by the X-ray diffraction (XRD) method. The differential scanning calorimeter (DSC) method is used to get the crystallization temperature and crystallization energy (Ea). It was found that proper Sn-doping could highly improve storage performance of the Ge_(2)Sb_(2)Te_(5) media.

本文介绍30兆赫彩色电视模拟信号传输特性的实验，它采用1.3微米波长的半导体激光二极管，传输距离超过17公里，且具有40.3分贝的非权加信噪比。当使用1.3微米激光二极管和低损耗单模纤维时，传输距离超过30公里。
加热单模光纤可以增大光纤等效纤芯半径，进而增大单模光纤的模场。根据粒子扩散方程建立了加热扩芯光纤的理论模型，并对其模场特性进行了数值分析。对两种单模光纤进行了加热扩芯技术实验研究，将模场直径增大3倍左右。监测了加热扩芯带来的损耗，实验发现掺杂浓度更高的单模光纤加热扩芯损耗更小。
采用射频等离子体分子束外延(RF-MBE)技术在蓝宝石(Al2O3)衬底上外延生长了InN薄膜, 在生长之前对其进行不同时间的氮化处理。通过扫描电子显微镜(SEM)和X射线衍射(XRD)对薄膜的形貌和结构进行了表征, 发现氮化时间小于60min时获得的InN薄膜的晶体结构为多晶且表面粗糙, 而氮化时间为60min及120min时获得的InN薄膜为单晶结构, 表面粗糙度有所下降。分析表明, 氮化时间对InN薄膜的晶体结构有很重要的影响。
以激光二极管阵列抽运Nd∶YAG内腔倍频激光器作为抽运源,实现了全固态准连续钛宝石激光器的高功率、高效率运转。当532 nm的抽运光为24 W时,得到了4.7 W输出功率及19.6%的高转换效率。为了获得钛宝石激光器理想的宽带输出,分别使用了两组膜片。第一组是750～850 nm,第二组是850～950 nm,每组膜片都有三种透过率,分别为5%,10%,15%。由于钛宝石荧光谱线的中心波长在795 nm附近,使用第一组膜片在透过率为10%的情况下获得了最大4.7 W的输出功率。使用第二组膜片也获得了3 W
针对单次扫描角度不同引起的夹杂检测误差较大、稳定性低等问题,提出了一种低密度粉末材料的多角度数字化X射线摄影(DR)扫描夹杂检测方法。首先对被测对象进行多角度DR检测;然后采用尺度不变特征变换(SIFT)特征匹配的方法寻找不同角度下夹杂的图像,自动选取不同角度下夹杂尺寸的最大值作为近似值;最后建立不同角度下夹杂面积和旋转角度的关系,并预测出夹杂的最大面积和旋转角度。实验结果表明,所提方法解决了计算
