A linear array of three identical lasers that are coupled mutually in space is investigated theoretically by integration of the laser equations. It is shown that the generalized synchronization of phase differences in the laser fields appears with intermediate coupling when the laser intensities are totally chaotic and chaotically synchronized. Both intensities and phase differences are totally chaotic at smaller coupling constants. The lasers are also changed from coherent light to incoherent one when the couplings between lasers are decreased.

Optimizing efficiency of organic light-emitting diodes（OLEDs） with a structure of Al/glass/nanometerthick polycrystalline p-Si（NPPS） anode/SiO_2/N＇-bis-（1-naphthl）-diphenyl-1,1＇-biphenyl-4,4＇-diamine（NPB）/tris（8-hydroxyquinoline） aluminum（Alq_3）/4,7-diphenyl^（-1）,10-phenanthroline（BPhen）：Cs_2CO_3/Sm/Au were studied. The NPPS anodes were fabricated by magnetron sputtering（MS）Si and Ni layers followed by Ni-induced crystallization of the amorphous Si layers. By adjusting the resistivity of the p-Si target adopted in MS, the electroluminescent efficiency of the OLED was optimized. When the resistivity of the p-Si target is 0.01 Ω·cm, the current and power efficiency of the NPPS anode OLED reach maximum values of 6.7 cd ·A^（-1）and 4.64 lm ·W^（-1）, respectively, which are 2.7 and 3.1 times those of the resistivity-optimized bulk p-Si anode counterpart and 2.9 and 3.7 times those of the indium tin oxide（ITO） anode counterpart, and then, the physical reasons were discussed.

针对目前汽车玻璃生产中,玻璃质量检测还大量依赖人工的问题,对YOLOv5s模型进行改进,提出了CSi-YOLOv5s的缺陷检测算法,用于实现汽车玻璃3类花点缺陷(黏连、残缺、缺失)的自动检测。首先,在Backbone部分的CBL模块中加入注意力模块CBAM,强化特征提取网络对多种花点缺陷特征的学习能力。其次,通过将激活函数改变为SiLU来优化深度网络的训练效果。对比实验数据表明,所提出的CSi-YOLOv5s花点缺陷检测算法对经过训练的3种花点图案的平均检测精度mAP达到99.1%,每张图像的平均检测时间小于0.15s。该算法对未经训练的4种花点图案的平均检测精度mAP也达到89.9%。算法实现了花点图案中微小缺陷的检测和分类,为汽车玻璃生产过程的缺陷检测提供了一种高效、实用且满足实时在线检测需求的解决方案。
