Laser Cooling

A variety of techniques for reducing the temperature (i.e., the random motion) of small particles.

Laser cooling is usually not meant to be the cooling of lasers, but rather the use of dissipative Light forces for reducing the random motion and thus the temperature of small particles, typically atoms or ions. Depending on the used mechanism, the achieved temperature can be in the regime of millikelvins, microkelvins, or even nanokelvins.
