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。

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
