Single-Shot Diffractive Imaging with a Table-Top Femtosecond Soft X-Ray Laser-Harmonics Source

• Coherent x-ray diffractive imaging is a powerful method for studies on   nonperiodic structures on the nanoscale. Access to femtosecond dynamics   in major physical, chemical, and biological processes requires   single-shot diffraction data. Up to now, this has been limited to   intense coherent pulses from a free electron laser. Here we show that   laser-driven ultrashort x-ray sources offer a comparatively inexpensive  alternative. We present measurements of single-shot diffraction patterns from isolated nano-objects with a single 20 fs pulse from a   table-top high-harmonic x-ray laser. Images were reconstructed with a   resolution of 119 nm from the single shot and 62 nm from multiple shots.
