Summary
[edit]DescriptionDoppler laser cooling.svg |
English: Simplified principle of Doppler laser cooling:
(1) A stationary atom sees the laser neither red- nor blue-shifted and does not absorb the photon. (2) An atom moving away from the laser sees it red-shifted and does not absorb the photon. (3.1) An atom moving towards the laser sees it blue-shifted and absorbs the photon, slowing the atom. (3.2) The photon excites the atom, moving an electron to a higher quantum state. (3.3) The atom re-emits a photon. As its direction is random, there is no net change in momentum over many atoms. |
