Lasers fire beams of light that can cut through steel or etch microchip patterns, depending on the power and wavelength. Now one team of scientists at the SLAC National Accelerator Laboratory in Menlo Park, Calif., led by Nina Rohringer, has created an X-ray laser that fires more energy, with a more precise wavelength, than any previous model. The results are being published in the journal Nature.
