An apparatus for localized transmittance measurements of optical coatings with spatially non-uniform performance is presented. The setup allows spectral acquisition in the range of 400–1000 nm with spatial resolution higher than 20 μm. Examples of its implementation for the characterization of linearly variable optical components of portable spectrometers are given.

为了更深层次探究超短脉冲激光对惯性约束聚变(ICF)光学系统中常见的多膜层元件损伤修复性能以及特点，分别采用了240、35、6 ps的1053 nm激光脉冲在1053 nm 0°高反膜上进行了损伤修复以及损伤增长测试实验，并在1053 nm 45°高反膜上进行了大损伤区域的扫描修复实验。通过比较不同脉宽的修复点形貌以及损伤增长阈值，说明了超短脉冲用于修复多膜层光学元件损伤的优越性，并且脉宽越短修复效果越好。多点脉冲扫描修复结果表明，可以通过三维控制系统来任意控制扫描修复点形貌以达到最佳修复状态。

提出了基于复合型光栅组合的多色集束匀滑方案,可实现激光集束在靶面上平移和旋转两种运动方式的组合。建立了靶面散斑的横向扫动速度物理模型,并推导出激光束横向扫动速度的解析表达式,进而讨论了靶面横向扫动速度的变化规律。在此基础上,分析了不同复合型光栅组合对靶面辐照均匀性的影响,并对复合型光栅参数的选取进行了优化。结果表明,与传统的线性光栅色散匀滑方案相比,在使用复合型光栅时激光束靶面散斑的扫动速度和扫动方向更加复杂,因而其匀滑效果更佳。与典型的束匀滑方案进行对比,经过优化的基于复合型光栅组合的多色集束匀滑方案能
