Multiphoton detachment of a negative ion by an elliptically polarized, monochromatic laser field
TL;DR: In this paper, a weakly bound electron with an energy E 0 in the threedimensional δ-model potential (which approximates the short-range potential of a negative ion) interacting with a strong monochromatic laser field having an electric vector F (ωt) is considered.
Threshold-related enhancement of the high-energy plateau in above-threshold detachment.
TL;DR: Nonperturbative theoretical results are presented showing a resonant-like enhancement of above-threshold detachment spectra in the region of the high-energy plateau as the laser intensity sweeps across channel thresholds.
Threshold-related effects in high-order harmonic generation
TL;DR: In this article, the exact ab initio quantum results for harmonic generation by a weakly bound electron interacting with a strong monochromatic laser field are presented, and the analytic structure of the HG amplitude resulting from the multiphoton detachment thresholds is demonstrated.
Threshold effects on angular distributions for multiphoton detachment by intense elliptically polarized light.
TL;DR: Unusual threshold effects are found theoretically in the frequency and intensity dependence of angular distributions produced by an elliptically polarized laser as well as in the elliptic dichroism parameter, which measures the asymmetry of the angular distribution.
Stabilization of Bound State Decay in an Intense Monochromatic High-Frequency Field
TL;DR: In this paper, the authors used complex quasienergies for exact calculation of the field-dependent decay rate for a weakly bound particle (in the model of a three-dimensional zero-range potential) in a strong monochromatic laser field.
