Second beamline now in operation at deep infrared FEL at Dresden

At the Forschungszentrum Rossendorf (FZR) in Dresden, Germany, the second undulator of the free-electron laser facility has gone into operation, producing light up to the hard-to-access range of the deep far infrared. The Dresden FEL now covers the wavelength range, invisible to humans, from 3 to 150 micrometers. The asset of every free-electron laser is its tunability, i.e., the wavelength or the color of the light can be adjusted at will over a large range. Scientists at FZR have a particular interest in this far-infrared light, which is located between the ranges of microwaves and the infrared and is often called Terahertz (THz) radiation. At FZR, THz radiation is used in particular to study the dynamical behavior of electrons in semiconductor nanostructures.
