摘要: We demonstrate the generation of a coherent water window x ray by extending plateau region high-order harmonics under neutral-medium condition. The maximum harmonic photon energies attained are 300 and 450 eV in Ne He, respectively. Our proposed scheme, combining $1.6\text{ }\text{ }\ensuremath{\mu}\mathrm{m}$ laser driver neutral gas medium, is efficient scalable output yields ray. Thus, precept design parameter for single-shot live-cell imaging contact microscopy presented.
