In case you missed the news last week, researchers converted the energy of an electron beam into a pulse of coherent light with an efficiency of 30 percent. If you need perspective, this is much higher than the 10 percent efficiency of most free-electron lasers.
According to the breaking news story by PhysicsWorld.com, while the demonstration produces only infrared light, the method could lead to efficient, high-power lasers operating over a range of wavelengths, including X-ray. X-ray sources like these could be used to etch circuits on semiconductor chips even faster.
At the Brookhaven National Laboratory, a research institute in Upton, New York, the energy conversion was demonstrated by first accelerating a beam of electrons in a five-metre-long tunnel. They then directed those electrons for several more metres along a helical path using magnets, before illuminating those electrons with an infrared laser.
