... beam with the stabilised frequency w1 = n33 effectively interacts with pump radiation only via the single common group of atoms, whose velocity projections are close to the zero value. Thus, the sole L-system 6S1/2(F = 3) – 6P3/2(F¢ = 3) – 6S1/2(F = 4) mainly contributes to the CPT resonance in abso ...

... The first basic concept we need is that of bound states. Atoms are held together by the attractive force between the positively-charged nucleus and the negatively-charged electrons: the electrons are bound to the atom, rather than being free to move though space. In the limit where the electron is v ...

... Physically, Eq. (5) represents a four photon process: absorption of a laser photon by one atom followed by coherent exchange of the excitation between the atoms via a virtual photon emission and aborption, and finally stimulated emission of a laser photon returning both atoms to the ground state.

Population inversion

In science, specifically statistical mechanics, a population inversion occurs while a system (such as a group of atoms or molecules) exists in a state with more members in an excited state than in lower energy states. It is called an ""inversion"" because in many familiar and commonly encountered physical systems, this is not possible. The concept is of fundamental importance in laser science because the production of a population inversion is a necessary step in the workings of a standard laser.
