Simultaneous Cooling, Concentrating of Light Creates Superphoton
BONN, Germany, Nov. 24, 2010 — By devising a way to cool and control light at the same time, a "gas" of photons was made to form the ultracold, high-density quantum state known as a Bose-Einstein condensate. Such photon-filled condensates, thought to be impossible to create until recently, could potentially serve as a new source of light for lasers that work in the x-ray range or in more powerful computer chips.
