Account of Stanford's X-ray laser in Nature Photonics

As reported here previously, in April this year, the first 1.5 Å wavelength laser light was generated at Stanford, USA. An interesting account of the hard X-ray laser was published in Nature Photonics. See the article, "Free electron lasers: First light from hard X-ray laser", B. McNeil, Nature Photonics, 3, 375-377 (2009).
