optical pumping. The rubidium atoms absorb photons and get energy of (μ 0 g F B) to break thermodynamic equilibrium. Traditionally, optical pumping experiments focus on single photon absorption, whereas we analyze multiphoton absorption. Take twophoton absorption (TPA) as an example of multiphoton absorption.
