The whispering gallery mode (WGM) based micro-bottle resonator (MBR) sensor has been proposed and demonstrated for relative humidity measurement by using an agarose gel as a transducer. MBR was fabricated by using a soften- and-compress method to form a 1

The single cavity all-dielectric thin film Fabry-Perot filter (s-AFPF) is investigated in this letter as a means of tuning the wavelength in an external cavity diode laser (ECDL), and the means of limiting longitudinal mode hopping is also investigated. W
利用2002-2008年间在我国渤海葫芦岛、东海平潭岛、东山岛以及南海的永兴岛等海域开展的海上试验观测数据,通过Bulk通量算法与射线程序统计分析了特征高度、折射率结构常数(C2n)等物理量以及光电系统相关传播参数的累积概率特征。东山岛海域特征高度大于零的情况占到90%以上,高C2n的情况(C2n
A math model that can describe the effect of stimulated Raman scattering (SRS) on pilot-tone detection technique is proposed. Through numerical simulation, it is shown that the effect of SRS could produce ghost-tones. The power of ghost-tones was larger f
基于所制备的高品质法布里-珀罗(F-P)光学微腔, 研究了一种基于激光信号的腔内高灵敏度熔解(HRM)曲线检测方法, 即将F-P光学微腔作为微激光腔, 将嵌入式饱和染料作为增益介质, 以产生的激光信号作为检测信号, 通过温度扫描, 实现了对碱基错配DNA分子的高灵敏度检测与筛查。分别研究了25个碱基对和50个碱基对的目标DNA及碱基错配DNA的熔解曲线, 理论及实验结果表明：基于激光信号的HRM检测技术具有低的熔解温度和高的信噪比。
采用脉冲Nd:YAG激光对锆4合金的十字交叉焊点进行试验研究，从焊点形貌、焊点成形系数和力学性能方面，研究了脉冲激光工艺参数对锆4合金十字交叉点焊的影响规律。研究表明：脉冲能量较小时，激光热量输入不能充分熔化交叉焊点预留凸台，焊点余高较大，无法满足实际应用要求。在单位脉冲能量一定的前提下增大峰值功率减小脉冲宽度，或增大激光脉冲的发射个数均可改善焊点的成形，减小焊点余高，得到较大的焊点深宽比。十字交叉焊点的最大拉伸载荷与焊点的深宽比成正比关系。
利用改进的化学汽相沉积工艺加溶液掺杂法,配合光学加工技术,自行设计并研制出内包层为矩形等新颖结构的掺Yb3 双包层石英光纤,实现了上述光纤的包层抽运激光器的成功运转.矩形光纤在1075.6 nm波长处获得84 mW的最大激光输出功率,斜率效率达77%.
Characterizing the luminescent properties of upconversion nanoparticles in single and densely packed
Luminescent properties of Er3 - and Yb3 - co-doped CaF2 upconversion nanoparticles (UCNPs) were investigated in single particle and densely-packed states with a custom-built microscope. The single UCNPs exhibit linear depe
