Laser cooling of molecules

A recent progress on laser cooling of molecules is summarized. Since the development during 1980s for atomic species, has been very beginning step to cool and trap atoms frontier research quantum simulations, sensing precision measurements. Despite complex internal structures molecules, have realized with deepened understanding molecular interaction between light molecules. The technology over last decades also a great aid because many lasers are necessary successfully detailed principle as well current status field reviewed give an introduction growing ultracold physics.
