“…One can see that the efficiency reaches ∼ 97% for sufficiently high twophoton Rabi frequencies and chirp rates, providing adiabatic interaction between atoms and laser pulses. Adiabaticity requires that |dδ/dt| ≪ Ω 2 and |dδ/dt|τ 2 p,S ≫ 1 [19], where dδ/dt = 2α is the two-photon chirp rate, as well as equal Rabi frequencies Ω p = Ω S , pulse durations τ p = τ S and chirp rates of the pump and Stokes pulses. From Fig.3a one can see that the efficiency becomes high (∼ 90%) for α ≥ 300 MHz/µs and Ω ≥ 30 MHz because for these parameters (using pulse durations τ p = τ S ∼ 0.1 µs) the adiabaticity conditions are satisfied: Ω 2 /2α ≈ 4.5 and 2ατ 2 p,S ≈ 38.…”

We analyze excitation of two ground state atoms to a double Rydberg state by a two-photon chirped optical pulse in the regime of adiabatic rapid passage. For intermediate Rydberg-Rydberg interaction strengths, relevant for atoms separated by ∼ten µm, adiabatic excitation can be achieved at experimentally feasible Rabi frequencies and chirp rates of the pulses, resulting in high transfer efficiencies. We also study the adiabatic transfer between ground and Rydberg states as a means to realize a controlled phase gate between atomic qubits.

“…Previous studies questioned the utility of AP in multi-level molecular systems interacting with strong femtosecond pulses [28,29]. In this work we put to test the techniques of two-photon rapid adiabatic passage (RAP [30,31]), stimulated rapid adiabatic passage (STIRAP [23]) and "piecewise AP" [32,33]. The latter approach has been proven successful in atomic systems [27,34] but has not been implemented with molecules.…”

This work investigates the utility of femtosecond pulse shaping in increasing the efficiency of Raman excitation of molecules in the strong-field interaction regime. We study experimentally and theoretically the effect of pulse shaping on the strength of non-resonant coherent anti-Stokes Raman scattering in iodine vapor at laser intensities exceeding 10 13 W/cm 2 . We show that unlike the perturbative case, shaping strong non-resonant laser pulses can increase the signal strength beyond that observed with the transform-limited excitation. Both adiabatic and non-adiabatic schemes of excitation are explored, and the differences of their potential in increasing the excitation efficiency are discussed.

“…A more robust method for creating a population inversion is through rapid adiabatic passage (RAP), 10,[12][13][14][15][16][17] as will be considered here. This technique has previously been described theoretically 10,12,18 and demonstrated experimentally in atomic systems including metastable helium 17 and dysprosium.…”

Highly efficient preparation of molecules in a specific rovibrationally excited state for gas/surface reactivity measurements is achieved in a molecular beam using tunable infrared (IR) radiation from a single mode continuous wave optical parametric oscillator (cw-OPO). We demonstrate that with appropriate focusing of the IR radiation, molecules in the molecular beam crossing the fixed frequency IR field experience a Doppler tuning that can be adjusted to achieve complete population inversion of a two-level system by rapid adiabatic passage (RAP). A room temperature pyroelectric detector is used to monitor the excited fraction in the molecular beam and the population inversion is detected and quantified using IR bleaching by a second IR-OPO. The second OPO is also used for complete population transfer to an overtone or combination vibration via double resonance excitation using two spatially separated RAP processes. © 2014 AIP Publishing LLC.
