10-12-22 December is a time for twinkling lights, and scientists at the Department of Energy's Thomas Jefferson National Accelerator Facility are delivering. They've just produced a long-sought, rare color of laser light 100 times brighter than that generate...

10-12-15 The manufacturing of semiconductor wafers（半导体薄片） used in all types of electronics involves etching（蚀刻） small features onto a wafer with lasers, a process that is ultimately limited by the wavelength of the light itself. The semiconductor...

10-11-26 Physicists from the University of Bonn have developed a completely new source of light, a so-called Bose-Einstein condensate（冷凝物，浓缩物） consisting of photons. Until recently, expert had thought this impossible. This method may potentially be...
