Generation of narrowband inversion with broadband laser pulses
We show experimentally, here for Na vapor, and theoretically that picosecond frequency-swept laser pulses create in multilevel systems an inversion profile that is far narrower than the pulse spectrum. This selectivity persists even when the Rabi frequency is substantially larger than the spacing between pumped and suppressed transitions. © 1992 The American Physical Society.
