AWhat changed
Related atomic transition probabilities to thermal radiation, distinguishing emission processes and absorption and developing the induced-emission mechanism later used in coherent light sources.
Scientific scope
Related atomic transition probabilities to thermal radiation, distinguishing emission processes and absorption and developing the induced-emission mechanism later used in coherent light sources. Scope limitation: The scoped record is the 1917 radiation paper, with 1916 antecedents acknowledged. It is neither a working laser nor a claim to own later maser and laser engineering. The historical terminology and assumptions differ from modern quantum electrodynamics.
