All the Colors of a High-Energy Rainbow, in a Tightly Focused Beam

For the first time, researchers have produced a coherent, laser-like, directed beam of light that simultaneously streams ultraviolet light, X-rays and all wavelengths in between.

One of the few light sources to successfully produce a coherent beam that includes X-rays, this new technology is the first to do so using a setup that fits on a laboratory table.

An international team of researchers, led by engineers from the National Science Foundation’s Engineering Research Center (ERC) for EUV Science and Technology, reports its findings in the June 8, 2012, issue of Science.
