Fig. 10: Extrapolating using simulations.
From: 2D transverse laser cooling of a hexapole focused beam of cold BaF molecules
The simulated relative molecule flux per shot (a, b) and beam size σ (c, d) for increasing laser cooling interaction length are shown. The flux is normalized to the simulated flux with a hexapole voltage of 0 kV and the cooling light turned off. Here, we use three different scattering efficiencies of η = 0.06, 0.12, 0.24, and a hexapole voltage of 2.0 kV (yellow, orange, red) or 3.5 kV (light blue, dark blue, purple). Installing two laser cooling vacuum chambers provides a total interaction length of 28 cm. The cooling parameters are Δ = − Γ, s = 4, α = 0. 5∘ with angles of βx, βy = 0.05∘ for each cooling direction.
