Using numerical simulations of two-photon electronic absorption with femtosecond pulses in Na2 we show that: (i) it is possible to avoid the characteristic saturation or dumped Rabi oscillations in the yield of absorption by time-delaying the laser pulses; (ii) it is possible to accelerate the onset of adiabatic passage by using the vibrational coherence starting in a wave packet; and (iii) it is possible to prepare the initial wave packet in order to achieve full state-selective transitions…

Nonresonant electronic transitions induced by vibrational motion in light-induced potentials.
We find a new mechanism of electronic population inversion using strong femtosecond pulses, where the transfer is mediated by vibrational motion on a light-induced potential. The process can be

Systems in which a near degeneracy of terminal state levels results in nonselective population of the terminal levels using nonchirped STIRAP or two-photon absorption stimulated passage are considered, because the dynamics within the nearly degenerate pair of levels is not adiabatic.
General theory of population transfer by adiabatic rapid passage with intense, chirped laser pulses
Abstract:We present a general theory of adiabatic rapid passage (ARP) with intense, linearly chirped laser pulses. For pulses with a Gaussian profile and a fixed bandwidth, we derive a rigorous
Light-induced trapping of molecular wave packets in the continuum
A method to prepare molecules in nonequilibrium nuclear configurations is proposed. By using strong laser fields it is possible to stabilize the dissociative continuum of an electronic potential.
Adiabatic passage by light-induced potentials in molecules
We present the APLIP process (Adiabatic Passage by Light Induced Potentials) for the adiabatic transfer of a wave packet from one molecular potential to the displaced ground vibrational state of
Controlling Non-Franck−Condon Transitions: Counterintuitive Schemes of Population Transfer in the Adiabatic and Strong Adiabatic Regimes†
Vibrationally selective population transfer in electronic transitions involving small Franck-Condon factors is studied by means of two-photon excitation with pulse sequences applied in
Ultrafast Population Inversion without the Strong Field Catch: The Parallel Transfer.
By properly choosing the relative phases of the initial state, one can interfere in the stimulated emission process, changing the pattern of Rabi oscillations so that full population inversion to the excited electronic state can be achieved almost regardless of the pulse intensity after a minimal threshold value.
Transferring vibrational population between electronic states of diatomic molecules via light-induced-potential shaping
We investigate two-photon, selective excitation of diatomic molecules with intense, ultrafast laser pulses. The method involves transfer of a vibrational population between two electronic states by
Coherent population transfer among quantum states of atoms and molecules
The authors discuss the technique of stimulated Raman adiabatic passage (STIRAP), a method of using partially overlapping pulses (from pump and Stokes lasers) to produce complete population transfer
Stimulated Raman adiabatic passage in a three-level superconducting circuit
The stimulated Raman adiabatic passage for circuit quantum electrodynamics is benchmarked by employing the first three levels of a transmon qubit by demonstrating a population transfer efficiency >80% between the ground state and the second excited state.
