In recent work published in Nature Photonics, Dennis Gardner and colleagues from the Murnane/Kapteyn group at JILA used the KMLabs XUUS4TM as a light source to achieve the 1st sub-wavelength EUV imaging for any light source, small or large. They also demonstrated coherent imaging of near-periodic samples with record 12.6 nm spatial resolution, at the technologically significant wavelength of 13.5 nm. The use of coherent EUV beams to implement coherent diffractive imaging has made it possible for the first time to advance EUV and x-ray imaging to near its theoretical resolution limit.
