WebbThe Rabi frequency is an expression of the light-matter interaction (Hamiltonian) and gives a relation between field polarization and electric dipole. Reading the book of Cohen-Tannoudji (Complement E X ), I have calculated the dipole transition elements of electronic states a D 1 m b (using Clebsch-Gordan coefficients). WebbAssuming that I=I_sat, the Rabi frequency is Gamma/sqrt (2). In the case of alkali atoms (widely used in laser cooling and trapping experiments), Gamma is about tens of MHz. So in this case the...
