Investigating ways of population transfer in atomic systems

In this lecture, while reviewing the interaction of the classical field with two- and three-level atoms in different configurations, we will examine different protocols for the effective transfer of atomic population in Λ-type three-level atoms. One of these protocols is called Raman pass-through protocol. In this method, a Hamiltonian is added to the original Hamiltonian of the system in such a way that the overall Hamiltonian of the system remains, especially the original Hamiltonian modes. The added Hamiltonian plays an important role for the complete transition of the atomic population by suppressing the non-immediate transitions.
