Recent research from the Institute of Optics and Atomic Physics at the Free University of Berlin has uncovered an exciting new way to measure the refractive index of materials in ultrafast X-ray and extreme ultraviolet (XUV) light. By using a special laser line, researchers were able to measure the refractive index of materials with unprecedented precision and speed. This research opens up the possibility of using these materials in a wide range of applications, from medical imaging to advanced manufacturing. The team is now working to develop a prototype device that can be used in a laboratory setting. This breakthrough could revolutionize the way we measure refractive indexes in XUV light and lead to a whole new world of possibilities.
