Uses
Laser cooling is primarily used for experiments in Quantum Physics to achieve temperatures of near absolute zero (−273.15°C, −459.67°F). This is done to observe the unique quantum effects that can only occur at this heat level. Generally, laser cooling has been only used on the atomic level to cool down elements. This may soon change, as a new breakthrough in the technology has successfully cooled a macro-scale object to near absolute zero.
