The use of broadband laser technology is a novel approach for inhibiting processes related to laser plasma interactions (LPIs). In this study, several preliminary experiments into broadband-laser-driven LPIs are carried out using a newly established hundreds-of-joules broadband second-harmonic-generation laser facility. Through direct comparison with LPI results for a traditional narrowband laser, the actual LPI-suppression effect of the broadband laser is shown. The broadband laser had a clear suppressive effect on both back-stimulated Raman scattering and back-stimulated Brillouin scattering at laser intensities below 1 × 10¹⁵ W cm^-2. An abnormal hot-electron phenomenon is also investigated, using targets of different thicknesses.

设计合成了一种以蒽［2，3?b］苯并呋喃为核心的新型化合物，通过给体咔唑基团修饰得到化合物2?（蒽［2，3?b］苯并呋喃?3?基）?9?苯基?9H?咔唑（ABPCz）。经过掺杂器件研究，ABPCz可以实现蓝光发射，最大电流效率为8.79 cd/A，最大外量子效率为7.8%，CIE（0.17，0.23），峰值光谱448 nm，在476 nm处有较强的肩峰，在 1 000 cd/m²初始亮度下测试器件LT90（亮度衰减到初始亮度的90%）寿命达到153 h。结果表明，蒽［2，3?b］苯并呋喃经过咔唑基修饰可以得到高效、长寿命的蓝光器件，这为设计开发高性能蓝光材料提供了一个新途径。

We experimentally transmit eight wavelength-division-multiplexing (WDM) channels, 16 quadratic-amplitude-modulation (QAM) signals at 32-GBaud, over 1000 km few mode fiber (FMF). In this experiment, we use WDM, mode division multiplexing, and polarization multiplexing for signal transmission. Through the multiple-input–multiple-output (MIMO) equalization algorithms, we achieve the total line transmission rate of 4.096 Tbit/s. The results prove that the bit error rates (BERs) for the 16QAM signals after 1000 km FMF transmission are below the soft-decision forward-error-correction (SD-FEC) threshold of 2.4×10-2, and the net rate reaches 3.413 Tbit/s. Our proposed system provides a reference for the future development of high-capacity communication.

针对当前液晶显示器前壳缝隙开口处的填充材料工艺设计复杂的问题，选取高导电性的金属粒子填充层作为导电面层，碳布层作为屏蔽面层，柔性硅橡胶作为中间基体层，设计一种层状结构导电橡胶。通过结构设计实现了导电橡胶低硬度和高导电性的协同。结果表明，当硅橡胶的硬度为35，体积电阻率为0.01 Ω·cm时可满足显示器产品的密封、防水和电磁屏蔽应用要求。
