WebSep 12, 2024 · We report on the simultaneous sub-Doppler laser cooling of 6Li and 7Li isotopes using gray molasses operating on their respective D1 atomic transitions. For 7Li we show that the sub-Doppler cooling can be achieved with two distinct Λ -type transitions, where the upper level can be either of the two 22P 1/2 hyperfine states. WebWe report on the production of Bose–Einstein condensates of sodium atoms in the hyperfine state F = 2, m F = 2 in a crossed optical dipole trap using D 2 gray molasses. We use the gray molasses sub-Doppler cooling technique to obtain an atomic sample of 3 …
WebJul 16, 2024 · We present a systematic study on the Raman gray molasses cooling (RGMC) of cesium atoms on the transition. Due to the large splitting in the excited hyperfine transitions of cesium line, it is relatively simple to implement the RGMC with suitable frequency control on the trapping and repumping lasers of the magneto-optical trap (MOT).
