Radiation interaction of Rydberg atoms and the one-atom maser

Spontaneous emission of a three-level atom in a system of N atoms

“…Experimental observations of spontaneous emission as well as collapses and revivals performed on two-level Rydberg atoms have proved the feasibility of testing the Jaynes-Cummings model (Haroche 1984, Haroche and Raimond 1985, Rempe and Walther 1985, Rempe et a1 1987. This, in turn, opens perspectives for the investigation of generalised Jaynes-Cummings models like that concerning the interaction of threelevel atoms with cavity-field modes.…”
