Doppler cooling is a technique used in atomic and molecular physics to reduce the temperature of a sample, typically of atoms or ions, by using the principles of the Doppler effect. It is particularly effective for cooling atoms to very low temperatures, near the absolute zero threshold, which allows for the study of quantum phenomena and precision measurements. The technique relies on the interaction between laser light and atoms.
