EUV–soft X-ray spectrometer - monochromator, and wavelength-tunable focusing mirror - all in one design Published in The Nature Light Journal A Twist of Fate in Optical Research: From a Budget Quip to Cutting-Edge Innovation Imagine you're shopping for a top-notch extreme ultraviolet (EUV) beam line grating, but the sales rep cheekily suggests you need at least €50,000 to play in the big leagues, or else, try your luck at Thorlabs or MKS. Sounds discouraging? Well, not for a team of audacious scientists from TU Wien, UCSD San Diego and CAS Beijing.! This seemingly derogatory remark didn't dampen our spirits, says Dimitar Popmintchev and Tenio Popmintchev – researchers from TU Wien and UCSD San Diego. Instead, it fueled a groundbreaking discovery, now celebrated in the Nature Light Journal. Monte-Carlo ray tracing of a-b Optimized spatial beam profile and chirp of a single high-order harmonic. c-d Unoptimized spatial beam profile and chirp of a single high-order
