Quantum Correlation Experiments with Resonance Fluorescence

... emitted as packets of light. Einstein then implied in a rate-equation model of the energy exchange between light and a black-body, that these light packets, which were later called photons, can be absorbed and spontaneously or stimulated emitted by atoms. It was then the use of the stimulated emissi ...

Level shifts of rubidium Rydberg states due to binary interactions
Level shifts of rubidium Rydberg states due to binary interactions

... Due to their large sizes and polarizabilities, Rydberg atoms excited from ensembles of laser-cooled ground state atoms interact strongly via resonant dipole-dipole or offresonant van der Waals interactions. These interactions can lead to a number of interesting collisional effects including state mi ...

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.
