In the work “Subwavelength coherent imaging of periodic samples using a 13.5 nm tabletop high-harmonic light source,” Dennis Gardner and colleagues from the Murnane/Kapteyn group at JILA, University of Colorado used the KMLabs XUUS4 as a light source for EUV imaging with record 12.6 nm resolution. The use of coherent EUV light to implement the coherent diffractive imaging technique, has made it possible for the first time to advance EUV and x-ray imaging to near its theoretical resolution limit.
