WebA Rabi cycle corresponds to one period of a Rabi oscillation. The angular frequency of the Rabi oscillations ( 2 π times the number of Rabi cycles per second) is called the Rabi frequency . It is 2 π times the product of the transition dipole moment of the optical transition and the electric field amplitude divided by Planck's constant.
