Interfering single photons retreived from collective atomic excitations in two dense cold-atom cloud
We report the Hong–Ou–Mandel (HOM) interference, with visibility of 91%, produced from two independent single photons retrieved from collective atomic excitations in two separate cold-atom clouds with high optical depths of 90. The high visibility of the
实验上,在线偏振和圆偏振强激光场中测得同核双原子分子O2在两个不同波长(800 nm和1500 nm)下的离子产量随光强变化曲线,发现其呈现出有趣的波长和偏振依赖关系: O2 产量在长波长下比短波长下更低,且不同波长间 O2 产量的差距在圆偏振光下相较线偏振下变得更大。利用散射矩阵(S-Matrix)理论模型定性地重复出实验结果,并从电子动量分布方面进一步确认了分子轨道效应对O2强场单电离的影响。
Transport network paths are typically bidirectional and symmetrical. In multi-protocol label switching (MPLS) and generalized MPLS (GMPLS) mechanisms, independent labels are distributed for bidirectional paths. Thus, the requirement of the MPLS transport
为了更好地研究叶绿素荧光特性和分析植物生长状况, 提出了从植物叶片微观结构的特点出发分析影响叶绿素荧光测量的一种研究方法。采用波长为460nm的LED作为光源激发叶绿素荧光, 经滤光片后, 通过CCD分别获取宏观叶绿素荧光和微观叶绿素荧光, 对荧光图像进行预处理并获得叶绿素荧光比率Rfd均值; 在显微镜下用CMOS获取叶片的显微图像, 测量上表皮厚度、栅栏组织厚度和叶片厚度等微观结构几何参数; 统计分析了叶片微观结构对宏观荧光测量的影响情况。结果表明, 对于像植物这种复杂的活体被测对象, 测量时应该考虑植

OFDM-based visible light communication with rotated polarity modulation aided complex color shift ke
High-rate techniques, such as optical orthogonal frequency division multiplexing (OFDM) and color shift keying (CSK), have been proposed for visible light communication (VLC). To fully exploit their advantages, in this Letter, we design a modulation schem
Wavelet modulus maxima method for on-line wavelength location of pulsed lidar in CO2 differential ab
Differential absorption lidar (DIAL) is an excellent technology for atmospheric CO2 detection. However, the accuracy and stability of a transmitted on-line wavelength are strictly required in a DIAL system. The fluctuation of a tunable pulsed laser system
Characterization of high nonlinearity in Brillouin amplification in optical fibers with applications
A highly accurate, fully analytic solution for the continuous wave and the probe wave in Brillouin amplification, in lossless optical fibers, is given. It is experimentally confirmed that the reported analytic solution can account for spectral distortion
