Extreme UV light made easy
A new system to generate coherent extreme-ultraviolet (EUV) light has been developed by researchers in Korea. The device, based on a nanostructure made of bow-tie shaped gold "antennas" on a sapphire substrate, is smaller and cheaper than existing systems and might allow a laptop-sized EUV source to be constructed directly from a single femtosecond light pulse. Applications include high-resolution biological imaging, advanced lithography of nanoscale patterns and perhaps "X-ray clocks".
