Figure B.3: Schematic <strong>of</strong> the cycling transition F = 2 → F ′ = 3 with the red detuned<br />
beam (orange) and the repump beam (blue). Energy is not to scale.<br />
interaction Hamiltonian becomes<br />
HB = µBgFFzBz. (B.2)<br />
In a weak external magnetic field the magnetic levels split according to the<br />
anomalous Zeeman effect. <strong>The</strong> perturbation <strong>of</strong> the interaction Hamiltonian to the zero<br />
field eigenstates is, to lowest order, given <strong>by</strong><br />
where<br />
gF ≈ gJ<br />
∆E = µBgFmFBz, (B.3)<br />
F(F + 1) − I(I + 1) + J(J + 1)<br />
