我们证明了在中性介质条件下，通过扩展高次谐波的平台区域来产生相干水窗X射线。在Ne和He中，获得的最大谐波光子能量分别为300和450 eV。我们提出的产生方案，结合1.6 μ m激光驱动器和中性Ne气体介质，是有效的和可扩展的水窗X射线的输出产量。因此，提出了接触显微镜单次拍摄活细胞成像的设计参数的方案。
We demonstrate the generation of a coherent water window x ray by extending the plateau region of high-order harmonics under a neutral-medium condition. The maximum harmonic photon energies attained are 300 and 450 eV in Ne and He, respectively. Our proposed generation scheme, combining a 1.6 mu m laser driver and a neutral Ne gas medium, is efficient and scalable in output yields of the water window x ray. Thus, the precept of the design parameter for a single-shot live-cell imaging by contact microscopy is presented.
