Calculated return flux for different conditions.

(a) Specific return flux ψ(I) for different polarization conditions and different angles between laser beam and magnetic field θ. CP stands for circular polarization and PS stands for polarization switching. (b) The calculated return flux ψ versus θ at a laser power intensity of 10 W/m2 with repumping power fraction of 0.1.
