Specific return flux in case of θ = π/2 and I = 10 W/m2.
(a) return flux ψ as function of repumping fraction q and (b) calculated return flux ψ versus angle between laser beam and magnetic field for both q = 0.1 and q = 0.2. Occupation probabilities evolution of the eight ground state’s magnetic sublevels at (c) q = 0.1 and (d) q = 0.2. The figure (c,d) share the same legend as in Fig. 3(b).
