Web1 gray molasses. The 1/e lifetime of atoms in the molasses is 50 ms. After being cooled for 1.5–2.0 ms, the temperature is as low as 40 μK without optical pumping or 60 μK after optical pumping into the F = 2,m F = 2 state for imaging and subsequent magnetic trapping. In contrast with [25], we find no further reduction in the steady-state
WebFeb 4, 2024 · Taken together, the successive gray molasses pulses cool all external degrees of freedom, which leads to an increase of the phase-space density (PSD) by a factor of ≈ 250, allowing to reach a high final PSD of ≈ 1.7 × 10 − 3.
