We summarize the development of high harmonic generation (HHG) with linearly polarized
Laguerre–Gaussian (LG) beams and their superpositions to explain the non-perturbative …

We experimentally investigate the single and double ionization of N 2 and O 2 molecules in
bicircular two-color femtosecond laser pulses, and compare with their companion atoms of …

Using the strong-field approximation we systematically investigate the selection rules for
high-order harmonic generation and the symmetry properties of the angle-resolved …

Using the improved molecular strong-field approximation we investigate high-order above-

We investigate photoelectron holography in bichromatic linearly polarized fields of
commensurate frequencies rω and sω, with emphasis on the existing symmetries and for …

We perform a systematic analysis of how ultrafast photoelectron holography is influenced by
an elliptically polarized field, with emphasis on quantum interference effects. We find that the …

Momentum-resolved photoelectron emission from xenon in colinearly polarized two-color
laser fields at above-threshold ionization conditions is studied both experimentally and …

Ionization of atoms by an intense bicircular laser field is considered, which consists of two
coplanar corotating or counterrotating circularly polarized field components with frequencies …

Improved molecular strong-field approximation theory is used to calculate the ionisation
probability for the high-order above-threshold ionisation process induced by a few-cycle …
