COHERENT POPULATION TRANSFER IN V-TYPE ATOMIC SYSTEM
Yasser Amoun Sharaby, Amitabh Joshi, Saad S. M. Hassan
In this paper, we investigate numerically the modeled density matrix equations for the interaction of a three-level atomic system in V-configuration with a train of chirped optical n-pulses (up to n = 10) within and without the rotating wave approximation. For adopted data of Rb 87, maximal population transfer to either of the upper levels is achieved with n > 1 pulse via variation of chirp parameter/frequency mismatch of the closely lying upper levels. Optimal steady population transfer and maximum atomic coherence of the upper levels are predicted for non-zero chirp parameter and train of n = 1 - 10, 30 pulses.
