Properties of the cooling, trapping, and push beams used to collect the data reported in Figs. 3–6. All transitions take place between the 2S_1/2 and the 2P_3/2 states in ⁷Li. F and F′ represent the ground and excited hyperfine states, respectively, though the excited state hyperfine structure is not well resolved. In cases where several beams overlap (i.e., in the MOTs), the intensity represents the total power delivered by all beams. For reference, the linewidth of this transition³¹ is Γ/2π $≈$ 5.9 MHz, and the saturation intensity is I_sat $≈$2.54 mW cm⁻².
