00:09 Lecture 6.6: Allowed Transitions, Selection Rules and Lasers
01:08 What happens when an electromagnetic wave "interacts" with an atom?
04:42 Optical transitions are not a time independent problem!
05:17 the interaction of an electron with the radiation field
07:42 An explicit equation for the spontaneous emission rate A21
10:02 Allowed Transitions in Atomic Hydrogen?
12:03 Important Implication
13:25 Light Amplification by Stimulated Emission of Radiation
