Better memory with faster lasers

DVDs and Blu-ray disks contain so-called phase-change materials that morph from one atomic state to another after being struck with pulses of laser light, with data "recorded" in those two atomic states. ...

Steps towards filming atoms dancing

With their ultra short X-ray flashes, free-electron lasers offer the opportunity to film atoms in motion in complicated molecules and in the course of chemical reactions. However, for monitoring this motion, ...
