Population transfer in ladder systems by means of frequency-swept ultrashort laser pulses

We report on experiments in which 100% population transfer is obtained in an atomic three‐level ladder system by means of frequency‐swept ultrashort laser pulses. Application to bond‐selective vibrational excitation and dissociation of molecules is discussed.

Efficient population transfer in a three-level ladder system by frequency-swept ultrashort laser pulses

Bernard Broers, H. B. van Linden van den Heuvell, Lambertus D. Noordam

Enhanced population transfer from the lowest to the highest level in the three-state ladder 5s\ensuremath{\rightarrow}5p\ensuremath{\rightarrow}5d of the rubidium atom by frequency-swept ultrashort laser pulses is observed if the frequency sweep first makes the pulse resonant with the 5s\ensuremath{\rightarrow}5p transition, and later with the 5p\ensuremath{\rightarrow}5d transition. With this ``intuitive'' scheme it is possible to achive complete population inversion via the intermediate level by two successive adiabatic passages. Complete inversion is also obtained by a ``counterintuitive'' direction of the frequency sweep, in which case population of the intermediate level during the pulse is strongly reduced.

Interference in climbing a quantum ladder system with frequency-chirped laser pulses

Péter Balling, D. J. Maas, Lambertus D. Noordam

Excitation of a quantum ladder system by frequency-swept (-chirped) laser pulses has been investigated by studying an atomic model system, the 5s-5p-5d ladder of rubidium. The population transfer is significantly enhanced when the frequency is swept such that it follows the spacing of the ladder. At intermediate intensities we observe oscillations in the population transfer to the upper level (5d), which can be attributed to interference between two routes of excitation: sequential transfer and direct two-photon excitation via a virtual intermediate state. We determine simultaneously the population transfer to the upper level (5d) and the direct three-photon ionization, the latter corresponding to a three-step ladder with the final state being in the continuum: 5s-5p-5d-\ensuremath{\varepsilon}p/\ensuremath{\varepsilon}f. Experiments were performed, using 100 fs pulses at \ensuremath{\sim}780 nm from a self-mode-locked Ti:${\mathrm{Al}}_{2}$${\mathrm{O}}_{3}$ oscillator amplified at 10 Hz.
