“…Figure 3 shows the maximum asymmetry A (m) and the corresponding phase ϕ m as function of the photon energy. We already predicted [41,49,52] that, within PT ∞ , the asymmetry always reaches its maximum value on both sides of the resonance, while the width of the structure depends on η and the ratio of the two-photon and one-photon ionization amplitudes. The former feature is seen in panels (a) and (b) of Fig.…”

“…In the first one, increasing η narrows the profile of the odd-rank anisotropy parameters β 1 and β 3 , and hence of the asymmetry (see Eqs. (23) and (30) of [52]). In the second one, increasing η reduces the asymmetry amplitude.…”

“…Besides its practical interest, considering bichromatic coherent control for resonant excitation of a 2p 5 4s state possesses a few important features: Ne (2p 5 4s) is much more correlated than the previously considered H (2p) [52] and Ne (2p 5 3s) [49] cases. Hence, it allows us to study the role of multielectron effects on coherent control.…”

Quantum coherent control of the photoelectron angular distribution in bichromatic-field ionization of atomic neon

We investigate the coherent control of the photoelectron angular distribution in bichromatic atomic ionization. Neon is selected as target since it is one of the most popular systems in current gas-phase experiments with free-electron lasers (FELSs). In particular, we tackle practical questions, such as the role of the fine-structure splitting, the pulse length, and the intensity. Time-dependent and stationary perturbation theory are employed, and we also solve the time-dependent Schrödinger equation in a single-active electron model. We consider neon ionized by a FEL pulse whose fundamental frequency is in resonance with either 2p − 3s or 2p − 4s excitation. The contribution of the nonresonant two-photon process and its potential constructive or destructive role for quantum coherent control is investigated.

“…Varying the XUV fundamental frequency near the intermediate 3s state leads to a Fano-like profile of the asymmetry at ML [9,49], which would be transferred to the sidebands by a sufficiently long IR pulse. To produce a selected control of the bands' asymmetry, an additional resonant path with nonequivalent effects on the different bands should be created.…”

We consider the ionization of neon induced by a femtosecond laser pulse composed of overlapping, linearly polarized bichromatic extreme ultraviolet and infrared fields. In particular, we study the effects of the infrared light on a two-pathway ionization scheme for which Ne 2s 2 2p 5 3s 1 P is used as intermediate state. Using time-dependent calculations, supported by a theoretical approach based on the strong-field approximation, we analyze the ionization probability and the photoelectron angular distributions associated with the different sidebands of the ionization spectrum. Complex oscillations of the angular distribution anisotropy parameters as a function of the infrared light intensity are revealed. Finally, we demonstrate that coherent control of the asymmetry is achievable by tuning the infrared frequency to a nearby electronic transition.

Coherent control with a short-wavelength free-electron laser

et al. 2016

Extreme ultraviolet and X-ray free-electron lasers (FELs) produce short-wavelength pulses with high intensity, ultrashort duration, well-defined polarization and transverse coherence, and have been utilized for many experiments previously possible only at long wavelengths: multiphoton ionization, pumping an atomic laser and four-wave mixing spectroscopy. However one important optical technique, coherent control, has not yet been demonstrated, because self-amplified spontaneous emission FELs have limited longitudinal coherence. Single-colour pulses from the FERMI seeded FEL are longitudinally coherent, and two-colour emission is predicted to be coherent. Here, we demonstrate the phase correlation of two colours, and manipulate it to control an experiment. Light of wavelengths 63.0 and 31.5nm ionized neon, and we controlled the asymmetry of the photoelectron angular distribution by adjusting the phase, with a temporal resolution of 3as. This opens the door to new short-wavelength coherent control experiments with ultrahigh time resolution and chemical sensitivity
