WebA simple application of the Stark-pulse technique, developed by Brewer and Shoemaker, demonstrates optical free induction decay-the optical analog of free induction decay … WebThis process is known as dephasing and can usually be quantified by a extinction rate of a coherence between states a and b: Γ a b. If the light field is turned off, coherent emission will decay exponentially at this dephasing rate. This is known as free induction decay (FID) . All mechanisms combine to produce the overall dephasing rate. This ...
