Extended Data Figure 4: MOT dependence on laser frequency.

Shown is LIF in the trapping region versus detuning when Δ₀₀ and are varied together (top), when is varied alone (middle) and when Δ₁₀ is varied alone (bottom). As expected (and typically observed for atomic MOTs), the SrF MOT operates over a fairly narrow range of negative detuning values for the trapping lasers but requires only that the repump lasers be sufficiently near resonance. Error bars, standard error for multiple scans across each detuning range (14 scans for top and middle; 24 scans for bottom).
