The intense X-rays from SOLEIL will be used for a range of experiments in physics, chemistry and biology. The machine is expected to come on-line in 2005. According to Schwartzenberg, the French gover...
In harmonic generation a short pulse of intense radiation is focussed into a gas of atoms. The laser-atom interactions are highly nonlinear, and a number of the input photons effectively combine to ge...
However, the resolution possible with scanning near-field optical microscopy (NSOM), as this approach is called, is essentially limited by the size of the aperture. To improve the resolution it is nec...
Klaus Dieter Liss from the European Synchrotron Radiation Facility in Grenoble, France, and colleagues have created a cavity that traps X-ray photons between two thin plates of silicon (Nature 404 371...
