Extended Data Fig. 1: Spectra of narrow-linewidth cooling lasers and their spatial extent.
The right side represents the spectra of cooling lasers addressing the 1S0–3P1 transition (vertical red bars) with respect to the (relative) energy of the states in the 3P1 manifold, shown on the left side. The energies of these \({m}_{{\rm{J}}}^{{\prime} }\) states are given depending on the location along the z axis, and the horizontal black dashed lines represent their respective Zeeman shifts when atoms are located inside the reservoir. The horizontal colour bars at the bottom left show the location and spatial extent of each laser beam; see also Extended Data Table 1 for detailed beam parameters.
