Low-energy peak structure in strong-field ionization by midinfrared laser pulses: Two-dimensional focusing by the atomic potential
Author(s): Christoph Lemell, Konstantinos I. Dimitriou, Xiao-Min Tong, Stefan Nagele, Daniil V. Kartashov, Joachim Burgdörfer, and Stefanie Gräfe We analyze the formation of the low-energy structure (LES) in above-threshold ionization spectra in strong-field ionization by midinfrared laser pulses by using both quasiclassical and quantum approaches. We show this structure to be largely classical in origin, [...]
