WebOct 1, 2024 · For the demonstration of our stray field compensation method, we use D1-line gray molasses cooling of K, but the technique can be applied to any species where cooling relies on coherences between hyperfine levels of the ground state. The key advantage of our approach is its speed. Gray molasses is a method of sub-Doppler laser cooling of atoms. It employs principles from Sisyphus cooling in conjunction with a so-called "dark" state whose transition to the excited state is not addressed by the resonant lasers. Ultracold atomic physics experiments on atomic species with poorly … See more Like Sisyphus cooling, the cooling mechanism of gray molasses relies on a two-photon Raman-type transition between two hyperfine-split ground states mediated by an excited state.
