Bridging the gap between conventional and large-scale,x-ray synchrotron tools to capture the shortest electron wavelengths and critical details of electronic interactions, the optics of a tabletop laser system allows for unprecedented characterization of electronic properties and illuminates new physics. A crystal and advanced gas path optics increase the energy of an infrared laser to the desirable extreme ultraviolet for experiments that degree the characteristics of electrons ejected from materials exposed to the laser beams. Scientists demonstrated the new system in experiments on a range of materials from semiconductors and superconductors to topological insulators, and which are exotic quantum materials that carry current on their surfaces.
