单个自由纳米粒子的相干衍射成像开辟了原位分析其瞬态结构，光学和电子特性的途径。到目前为止，单次单粒子衍射被认为只在极紫外和X射线自由电子激光器上可行，这一研究领域限制在大型设备上。在这里，我们展示了单次拍摄成像的孤立氦纳米液滴使用极紫外脉冲从飞秒激光驱动的高谐波源。我们获得明亮的广角散射图案，使我们能够唯一地识别迄今尚未解决的超流氦滴的扁长形状。我们的研究结果标志着单次气相纳米显微镜与实验室为基础的短波长脉冲的到来，并铺平了道路，超快相干衍射成像与相位控制的双折射场和阿秒脉冲。迄今为止，对自由纳米粒子的衍射成像研究仅限于XUV和X射线自由电子激光设备。在这里，作者证明了使用桌面XUV激光源来成像超流氦滴的扁长形状的可能性。
Coherent diffractive imaging of individual free nanoparticles has opened routes for the in situ analysis of their transient structural, optical, and electronic properties. So far, single-shot single-particle diffraction was assumed to be feasible only at extreme ultraviolet and X-ray free-electron lasers, restricting this research field to large-scale facilities. Here we demonstrate single-shot imaging of isolated helium nanodroplets using extreme ultraviolet pulses from a femtosecond-laser-driven high harmonic source. We obtain bright wide-angle scattering patterns, that allow us to uniquely identify hitherto unresolved prolate shapes of superfluid helium droplets. Our results mark the advent of single-shot gas-phase nanoscopy with lab-based short-wavelength pulses and pave the way to ultrafast coherent diffractive imaging with phase-controlled multicolor fields and attosecond pulses. Diffraction imaging studies of free individual nanoparticles have so far been restricted to XUV and X-ray free - electron laser facilities. Here the authors demonstrate the possibility of using table-top XUV laser sources to image prolate shapes of superfluid helium droplets.
