In the Bragg regime, however, with the initial and final states and coupled with an effective Rabi frequency proportional to the m-th power of , we must introduce another definition of pulse area. We therefore define the “2m-photon pulse area” as

(5.57)

Then, for a system initially in state , the probability of excitation to state after interacting with a very long pulse of intensity is given by

Table 5.1Summary of the different interaction regimes of atomic Bragg diffraction. The three regimes introduced so far are not ideal for interferometry: in the short interaction Raman-Nath regime the transfer efficiency to any particular state is very limited, whereas in the Bragg and channeling regimes the requirement of long interaction times will degrade the performance of the interferometer
