论文摘要
对于极端紫外线（XUV）和X射线脉冲的许多应用，小焦点大小对于达到所需的强度或空间分辨率至关重要。在本文中，我们提供了一种以1.85千分尺为单位的XUV焦点来表征XUV焦点的简单方法。此外，该技术用于测量和优化椭圆形镜的焦点，用于高阶谐波产生的18至150 eV的光子能量。我们设想通过通过同步激素到自由电子激光器从高谐波来源分辨率从高谐波来源分辨出这种方法的广泛应用。
For many applications of extreme ultraviolet (XUV) and x-ray pulses a small focus size is crucial to reach the required intensity or spatial resolution. In this article, we present a simple way to characterize an XUV focus with a resolution of 1.85 micrometer. Furthermore, this technique is applied for the measurement and optimization of the focus of an ellipsoidal mirror for photon energies ranging from 18 to 150 eV generated by high-order harmonics. We envisage a broad range of applications of this approach with sub-micrometer resolution from high-harmonic sources via synchrotrons to free-electron lasers.
