Strong-field physics is currently experiencing a shift towards the use of mid-IR driving wavelengths. This is because they permit conducting experiments unambiguously in the quasistatic regime and enable exploiting the effects related to ponderomotiv

Structural information on electronically excited neutral molecules can be indirectly retrieved, largely through pump–probe and rotational spectroscopy measurements with the aid of calculations. Here, we demonstrate the direct structural retrieval o

Strong field photoemission and electron recollision provide a viable route to extract electronic and nuclear dynamics from molecular targets with attosecond temporal resolution. However, since an {\em ab-initio} treatment of even the simplest diatomi

Visualizing chemical reactions as they occur requires atomic spatial and femtosecond temporal resolution. Here, we report imaging of the molecular structure of acetylene (C 2 H 2 ) 9 femtoseconds after ionization. Using mid-infrared laser–induced e

In order to probe molecular dynamics at few-femtosecond resolution we use laser-induced electron diffraction imaging driven by mid-IR electric waveforms. Combined with coincidence detection we can extract structural information of fragmentation pathw

Laser-induced electron diffraction is an evolving tabletop method, which aims to image ultrafast structural changes in gas-phase polyatomic molecules with sub-{\AA}ngstr\"om spatial and femtosecond temporal resolution. Here, we provide the general fo

We report the simultaneous retrieval of multiple bond lengths of the polyatomic molecule C 2 H 2 by coherent “self-electron” wave packets generated by the interaction of the molecular target with intense mid-IR laser pulses [1].

Atomic ionization by intense mid-infrared (mid-IR) pulses produces low electron energy features that the strong-field approximation, which is expected to be valid in the tunneling ionization regime characterized by small Keldysh parameters ($\gamma \

We present accurate extraction of multiple bond lengths for aligned and anti-aligned C2H2 using recollision electron diffraction. We measure bond lengths of1.20±0.06A (C≡C) and 1.06±0.08A (C-H).
