Rabi oscillations produced by adiabatic pulse due to initial atomic coherence. Academic Article uri icon

abstract

  • If an electromagnetic pulse is detuned from atomic transition frequency by amount >1/, where is the turn-on time of the pulse, then atomic population adiabatically follows the pulse intensity without causing Rabi oscillations. Here we show that, if initially, the atom has nonzero coherence, then the adiabatic pulse yields Rabi oscillations of atomic population aa(t), and we obtain analytical solutions for aa(t). Our findings can be useful for achieving generation of coherent light in the backward direction in the QASER scheme in which modulation of the coupling between light and atoms is produced by Rabi oscillations. Initial coherence can be created by sending a short resonant pulse into the medium followed by a long adiabatic pulse, which leads to the light amplification in the backward direction.
