Carrier Wave Rabi Flopping (CWRF)
Presentation by Nathan Hart
Conditions for CWRF:1. There must exist a one photon resonance with the ground state 2. The Rabi frequency between the ground state and the first excited
state must be on the order of the laser frequency Result of CWRF:1. Asymmetric Bloch sphere path for the block vector.2. Broad frequency generation resulting from beating between
βThe source for the CWRF is due to fast oscillations in the polarization equations outside the RWA.βHughes, S. "Breakdown of the area theorem: carrier-wave Rabi flopping of femtosecond optical pulses." Physical review letters 81, no. 16 (1998): 3363.
The laserβs electric field :The Rabi frequency :The pulse area Pulse Area Theorem: The laser pulse phase is not changed (only delayed in time) if the pulse area , where is an integer. Self-Induced Transparency
