We investigated nonlinear optical properties of ZnO-Nb_(2)O_(5)-TeO_(2) glass excited by a femtosecond laser with time-resolved four-wave mixing (FWM) technique. The unusual FWM signals were observed in samples with ZnO dopant. The mechanism for the optical nonlinearities was discussed.

A three-dimensional model of GaAs/AlGaAs quantum double rings in the lateral static electric field is investigated theoretically. The eigenvalue problem with the effective-mass approximation is solved by means of the finite-element method. The energy leve
The non-equilibrium between ions and electrons in the hot spot can relax the ignition conditions in inertial confinement fusion [Fan et al., Phys. Plasmas 23, 010703 (2016)], and obvious ion-electron non-equilibrium could be observed by our simulations of
本文研究了激光等离子体中由有质动力决定的准稳态密度分布,导出了局域密度标度长度、上、下密度平台长度和下平台平均密度标度长度对入射光场强和时间的依赖关系。结果表明,在达到准稳态后,随着时间的推移,上、下密度平台的长度和下平台平均密度标度长度增大,而临界密度区域的标度长度仅微小地增加,这些结果与实验及粒子模拟相一致。

Despite very efficient superconducting nanowire single-photon detectors (SNSPDs) reported recently, combining their other performance advantages such as high speed and ultralow timing jitter in a single device still remains challenging. In this work, we p

英国卢瑟福·阿普尔顿实验室的科学家已 在迄今为止最短的8.09纳米波长上实现了远紫外激光放大。该法是基于使用高度电离氟原子复合泵浦。倍频钕玻璃激光器(“火神”)输出的激光脉冲产生氟离子和电子组成的基本等离子体,它是强X射线源。“火神”高能激光脉冲被线聚焦到涂LiF膜的碳纤维上。这种复合激光器的一个可能应用是对生物标本成象。

在利用电迁移现象制备铝纳米线的过程中, 铝纳米线的生长位置取决于铝原子的积聚位置。为实现铝原子积聚位置控制, 基于纳米压痕技术改变试样中铝膜的横截面结构, 制备了铝膜试样。通过输入并调节直流电大小使铝膜内产生电迁移现象。试验结果表明, 纳米压痕技术可有效提高局部区域的电流密度, 显著增强铝原子的电迁移强度, 并在压痕区域出现铝原子积聚现象。
