Laser made from single atom The simplest possible laser -- a single atom -- has been on the drawing board for decades. Researchers have finally achieved the extremely precise control needed to make a laser from just one atom. The first demonstration of a single-atom laser showed that it's a different animal -- it produces quantum light. |
