X-ray microscopy: Light goes fourth

Scientists at high-energy physics labs around the world are working on the specification of the 'fourth-generation' light sources, based on free-electron laser synchrotrons, that will be capable of producing light of such extreme brilliance that new ways of focusing the radiation will have to be found. A device reported this week, based on the simple concept of an array of pinholes, could be the answer. The 'photon sieve' exploits the monochromaticity and coherence of light from an electron-free laser to focus soft X-rays with unprecedented sharpness. The combination of sharper focus with extreme brightness should herald a new era of high-resolution X-ray microscopy.
