Rabi frequency STIRAP

Because the Stokes pulse precedes but overlaps the pump pulse, initially Up and all population initially in field-free state 11) coincides with flo(0)- At the final time, ilp Q5 so all of the population in flo(0) projects onto the target state 6). Note that flo(0) has no projeetion on the intermediate field-free state 5 ). The Rabi frequencies of the Stokes and pump pulses that are required for efficient STIRAP-generated population transfer satisfy the condition [66]... 

The hopping rate is a function of R and site numbers as noted above, it will play the role of the half Rabi frequency of the Stokes and pump fields in a STIRAP process with Vq = 0. Assuming T pp(m, t) 0 (0 (m, R(t)) 0) we divide Eq. (3.120)... 

FIGURE 23 Illustration of the STIRAP technique used for coherent population transfer. Shown are the time evolution of (a) the Rabi frequencies of the pump and Stokes lasers, (b) the mixing angle, (c) the dressed-state eigenvalues, and (d) the populations of the initial and final levels.
