We demonstrate, to our knowledge, the first bright circularly polarized high-harmonic beams
in the soft X-ray region of the electromagnetic spectrum, and use them to implement X-ray …

In the last two decades, thanks to the considerable technological development of solid-state
sensors, digital holography (DH) has gained credits as the elective imaging technique for …

We demonstrate the first (to our knowledge) general purpose full-field reflection-mode
extreme ultraviolet (EUV) microscope based on coherent diffractive imaging. This …

Atoms undergoing strong-field ionization in two-color circularly polarized femtosecond laser
fields exhibit unique two-dimensional photoelectron trajectories and can emit bright …

High-harmonic generation driven by two-color counter-rotating circularly polarized laser
fields was recently demonstrated experimentally as a breakthrough source of bright …

Recent technological advances in attosecond science hold the promise of tracking
electronic processes at the shortest space and time scales. However, the necessary imaging …

Although holography is topic that goes back to the 1950s, the research in this field continues
to be very active worldwide. A continuous growth is confirmed by the publication of more …

Scanning electron microscopy and atomic force microscopy are well-established techniques
for imaging surfaces with nanometer resolution. Here we demonstrate a complementary and …

Lensless imaging is an approach to microscopy in which a high-resolution image of an
object is reconstructed from one or more measured diffraction patterns, providing a solution …

We report a proof-of-principle demonstration of a new scheme of spectromicroscopy in the
extreme ultraviolet (EUV) spectral range, where the spectral response of the sample at …
