Researchers at the SLAC National Accelerator Laboratory used the Linac Coherent Light Source to aim a powerful X-ray source beam, a billion times brighter than any previous source, at a capsule of neon gas and triggered an 'avalanche' of X-ray emissions to become the world's first 'atomic X-ray laser.'"
