Optical bloch equations three level system
Webthe optical Bloch equations are obtained. The Bloch equations are supposed to describe a two-level system with spontaneous relaxation from state 2i to 1i . This is not yet included in the derivation and requires a modification of equation 4.7 in such a way that in absence of a laser field the population ρ22 and thus c2 vanishes. WebJun 1, 2010 · The general solutions are given by η = η c 1 e λ 1 t + η c 2 e λ 2 t + η c 3 e λ 3 t + η s, where η = u, v, and w. The unknown values η c 1, η c 2, and η c 3 can be obtained …
