Abstract

Optical pumping is a process used in physics and quantum mechanics to manipulate the energy levels of atoms or ions using light. It involves the absorption and emission of photons by atoms, which can change their electronic configurations and energy states. In this paper, optical pumping with Liouville equation approach is used to investigate optical pumping in alkali atoms. For this purpose, circularly polarized light is applied to the atomic system, which causes a transition between atomic sublevels and changes the population of sublevels. Also effect of relaxation and repopulation are considered in the evolution of the population sublevels. Here, we use optical pumping with Liouville equation approach for investigation of population evolution in Cesium atom.
