我们提出并演示了一种在水窗口光谱区域以高达100赫兹的重复频率工作的相干激光-等离子体点X射线源。来自10μm直径光源的发射经过滤波以产生波长为3.37 nm的单色辐射。获得了杨氏干涉实验的软X射线条纹，能见度为0.6 2±0.1，狭缝间距为10.5μm，距光源31.7 cm。该光源可用于在几分钟的合理曝光时间内拍摄全息图或透射式扫描X射线显微照片。
We propose and demonstrate a coherent laser‐plasma point x‐ray source in the water window spectral region operating at a repetition rate of up to 100 Hz. The emission from the 10‐μm‐diameter source is filtered to generate monochromatic radiation at a 3.37 nm wavelength. Soft x‐ray fringes of the Young’s interference experiment were obtained with a visibility of 0.62±0.1 with a slit pair of 10.5 μm separation at a distance of 31.7 cm from the source. The source can be used to take either a hologram or transmission scanning x‐ray micrograph within a reasonable exposure time of several minutes.
