We present a table-top coherent diffraction imaging (CDI) experiment based on high-order harmonics generated at 18 nm by a high average power femtosecond fiber laser system. The high photon flux, narrow spectral bandwidth and high degree of spatial coherence allow for ultra-high sub-wavelength resolution imaging at a high numerical aperture. Our experiments demonstrate a half-pitch resolution of 13.6 nm, very close to the actual Abbe-limit of 12.4 nm, which is the highest resolution achieved from any table-top XUV or X-ray microscope. In addition, 20.5 nm resolution was achieved with only 3 sec of integration time bringing live diffraction imaging and 3D tomography on the nanoscale one step closer to reality. The current resolution is solely limited by the wavelength and the detector size. Thus, table-top nanoscopes with only a few-nm resolutions are in reach and will find applications in many areas of science and technology.Coherent diffractive imaging (CDI) is an imaging technique that provides amplitude and phase information of a nanoscale sample from diffraction patterns recorded in the far field. Since no optics is needed between the sample and the detector, it is scalable to smallest resolutions provided that a high photon flux short wavelength light source with good coherence is used for illumination. Despite huge technological efforts, the resolution of conventional X-ray microscopes is still limited to 12 nm to 20 nm [1][2][3] by the fabrication precision of the employed zone plates. In contrast, coherent diffractive imaging and related techniques demonstrated 7 nm [4] and 5 nm resolution [5] already which can be improved with the availability of a better source. Since the short wavelength light can, in contrast to electron beams, even shine through µm-thick samples exciting possibilities in damage-free 3-dimensional (3D) imaging with unprecedented resolution open up [6]. Furthermore, ultrashort X-ray pulses enable time-resolved movies of the fastest dynamics on the nanoscale [7] being relevant for future electronic, optical and magnetic devices. Unfortunately, the applicability of these imaging techniques in science and technology is limited due to the size, cost and accessibility of the typically desired light sources namely synchrotrons and free-electron lasers [8].The advantages of coherent nanoscale microscopy can only be fully exploited in all areas of science with a compact, reliable and powerful table-top implementation. Thus, laser-driven light sources based on high harmonic generation (HHG) [9,10] are considered as a promising alternative which can be implemented on a Clearly, real-world applications in nanoscience require shorter integration times and the smallest possible resolutions. Once the measurement times for a single high-resolution 2D image has been reduced to seconds, even 3D tomography or ptychographic imaging of large objects [13,14], which requires imaging of hundreds of individual diffraction patterns, get practically feasible with table-top setups.
