A large fraction of JILA research relies on laser cooling of atoms, ions and molecules for applications as diverse as world-leading atomic clocks, human-controlled chemistry, quantum information, new forms of ultracold matter and the search for new details of the origins of the universe. JILAns use laser cooling every day in their research, and have mastered arcane details of the process.

So it was a surprise when an accidental discovery in a JILA lab, coupled with new theory to explain that discovery, created an entirely new, more robust method of laser cooling, potentially advancing nearly all current JILA research using laser cooling, and opening new areas of research.

The new JILA laser cooling technique, dubbed SWAP cooling, uses stimulated emission, rather than spontaneous emission, to increase cooling forces. This new technique, detailed in a recent New Journal of Physics publication, is ideal for cooling atoms with narrow linewidth transitions, such as those with expansive frequency metrology applications (e.g., atomic clocks). The technique could also have applications...
