The Promise of Terahertz

Terahertz (THz) light may provide stunning breakthroughs in areas as diverse as national security, medical imaging and communications technology. But it's largely been ignored until recently, because there wasn't a terahertz light source bright enough for these applications. Now the Free-Electron Laser (FEL) at DOE's Jefferson Lab (JLab) is producing 100 Watts of THz light for scientific studies -- nearly 100,000 times brighter than THz light produced anywhere else.
