Remarks on the tunneling limit of strong-field photoionization

TL;DR

This paper generalizes previous results on strong-field photoionization to elliptical polarization and discusses the conditions under which tunneling ionization occurs in intense laser fields.

Contribution

It extends Reiss's work to elliptical polarization and provides insights into the tunneling limit of strong-field ionization.

Findings

Generalized Reiss's results to elliptical polarization

Analyzed the tunneling limit in strong-field ionization

Discussed conditions for tunneling regime

Abstract

Some results from a recent work of Reiss [Phys. Rev. Lett. 101, 043002 (2008); 101, 159901(E) (2008).] are generalized for the case of elliptical polarization of a laser field. We also discuss the tunneling limit of strong-field photoionization.
