The Bose-Einstein Condensate, that special form of matter whose conjecture earned Satyendra Bose and Albert Einstein the Nobel Prize, has again been produced - this time with photons.
Researchers have managed to trap photons in a resonant cavity with dye molecules, which act to redistribute photon energy in a manner resembling the statistical mechanics of a gas - the famous Bose-Einstain statistics. As the 'photon gas' reached a minimum critical density, the Photonic Bose-Einstein Condensate was produced, resulting in a laser.
This could end up becoming an entirely new alternative way to produce lasers. Consequently, new laser applications like high-energy lasers may be enabled, which were previously too difficult.
