Free-electron lasers (FEL) are large and expensive, but they can deliver unique light for research and applications. On August 21, 2006, at the Forschungszentrum Rossendorf (FZR) in Dresden, Germany, the second undulator of the free-electron laser facility went into operation, producing light up to the hard-to-access range of the deep “far” infrared.
