Broadband mid-infrared nonlinear optical modulator enabled by gold nanorods: towards the mid-infrare
Mid-infrared pulsed lasers operating around the 3?μm wavelength regime are important for a wide range of applications including sensing, spectroscopy, imaging, etc. Despite the recent advances in technology, the lack of a nonlinear optical modulator opera

软X射线成像需用高分辨率波带板(Zone plate)。本文分析了齐明系统非齐明点球差特性。利用这种特性可以产生制作高分辨率X射线波带板所需的两束非球面波。文中还给出了合肥国家同步辐射实验室光束线所用的软X射线波带板的结构参数和制造这种波带板的光学系统。
In this paper, we present the development and application of a full-aperture backscatter diagnostics system at the Texas Petawatt Laser (TPW) facility. The diagnostic system includes three independent diagnostic stations. With this system, we obtained TPW
报道了一种新的同可溶性好的，具有连苯结构的共轭有机聚合物：聚(2，5-二丁氧基)苯撑(简称PPP)，采用四波混频方法测量了它在532 nm和1064 nm处的三阶非线性光学系数，由此推算了非线性折射率，并讨论了材料的优质因子，指出了材料最适用的光波段。

To introduce ordered nano-structures inside a transparent amorphous matrix with superior optical and mechanical properties bears scientific and technological importance, yet limited success has been achieved. Here, via simple melting-quenching and subsequ
将波长1064 nm,脉冲宽度8 ns 的Nd:YAG 激光脉冲聚焦到FC-72 介质池中,利用CCD 对后向受激布里渊散射(SBS)光斑进行检测,并利用数字图像处理技术对图像进行分析,以获得SBS 光斑的空间光强分布和变化规律。利用MATLAB 的图像处理工具箱对激光光斑的原始CCD 图像进行去噪,并使用Origin 软件的曲线拟合和FFT 平滑功能对光强分布曲线进行平滑处理。结果表明,进行图像处理后的原图像噪声被有效地抑制和消除,光强分布曲线较为平滑。在入射光束为基模高斯光束的条件下,随着入射光能量增
Effect of higher order non-linearity in frequency variation of self-phase modulation in optical fibe
In optical soliton propagation through a single mode optical fiber, it is established that self-phase modulation is maintained by the third order non-linearity of the silica-based glass material of the fiber. In this paper we show that the fifth order non
美帝无线电公司用普通阴极射线管中的磷光体——氧化锌单晶——首次制成产生紫外光的固体激光器。他们研究出了一种透明的氧化锌小片，将这种小片装在金属支架上，放入真空玻璃管内，然后用高电压电子束轰击。
