In this paper, we present the luminescent properties of Tm3 ∕Ho3 co-doped new glass. A series of silicategermanate glass was prepared by the conventional melt-quenching method. In the Tm3 ∕Ho3 co-doped silicategermanate glass, a strong emission of 2 μm originating from the Ho3 :5I7 → 5I8 transition can be observed under conventional 808 nm pumping. The characteristic temperatures, structure, and absorption spectra have been measured. The radiative properties of Ho33 in the prepared glass were calculated. The emission cross section of Ho33 ions transition can reach 4.78 × 10?21 cm2 around 2 μm, and the FWHM is as high as 153 nm. The energy transfer efficiency between Ho3 and Tm3 has a large value (52%), which indicates the Tm3 ∕Ho3 co-doped silicategermanate glass is a suitable candidate for the 2 μm laser. Moreover, the energy transfer mechanism between Tm3 and Ho3 ions was investigated.(61370049, 61308090, 61405182, 51172252, 51372235, 51472225); International Science

实际应用中球差作为一种普遍存在的像差，对光束在光学系统中的传输具有较大影响。为了研究球差对光束通过分数傅里叶变换系统后所产生的影响，基于柯林斯公式，推导出余弦高斯光束在有球差和无球差的分数傅里叶变换系统中的场分布，并以Lohmann Ⅰ型系统为例，进行数值模拟计算，研究了余弦高斯光束通过有球差和无球差的分数傅里叶变换系统后输出面的横向光强分布规律以及不同变换阶数和不同调制参数下轴上光强大小与球差系数的关系。结果表明，在分数傅里叶变换系统中，透镜球差对输出面横向光强分布有较大影响，并且正球差和负球差对横向光
本文在考虑湍流内外尺度的情况下, 对部分相干高斯谢尔模型光束在大气湍流中的传输特性进行了研究.主要采用考虑湍流内外尺度的修正Von Karmon谱模型, 推导了部分相干光在大气湍流中的平均光强分布、光束扩展均方根束宽和漂移方差的解析式.对比分析了不同湍流强度情况下, 湍流内外尺度对部分相干光在大气湍流中水平和斜程路径上传输特性的影响.结果表明: 相同条件下, 光束在大气湍流中传输时, 沿斜程传输时的抗湍流能力强于水平传输; 相比于大气湍流内尺度, 大气湍流外尺度对光束漂移影响较大, 外尺度对光束扩展与光强

提出了一种基于量子粒子群优化算法的光纤光栅参数重构方法。该方法通过传输矩阵法得到优化目标函数，并将待优化的光纤光栅参数以粒子表示，再让粒子在解空间模拟量子行为进行搜索。以均匀布拉格光栅和线性啁啾光纤光栅为例，分别采用遗传算法（GA）、经典粒子群优化（PSO）算法以及量子粒子群优化（QPSO）算法对其进行参数重构。与传统粒子群算法及遗传算法相比，该方法借鉴了量子行为，具有更好的收敛性能和稳态性能。数值结果表明，种群规模为40时，针对均匀和非均匀光栅分别进化100代和200代得到的重构参数误差均小于0.5%。
