8.421 Atomic and Optical Physics I

8.421 Atomic and Optical Physics I (Spring 2014, MIT OCW). Instructor: Professor Wolfgang Ketterle. This is the first of a two-semester subject sequence that provides the foundations for contemporary research in selected areas of atomic and optical physics. Topics covered include the interaction of radiation with atoms: resonance; absorption, stimulated and spontaneous emission; methods of resonance, dressed atom formalism, masers and lasers, cavity quantum electrodynamics; structure of simple atoms, behavior in very strong fields; fundamental tests: time reversal, parity violations, Bell's inequalities; and experimental methods.

Lecture 22 - Coherence II

In this video, the professor reviewed spontaneous emission and discussed coherence in two-level systems.
