Frustrated tunnel ionization of argon by intense few-cycle infrared laser radiation

Abstract

We report results for strong-field ionization and excitation of argon obtained by solving the time-dependent; Schrödinger equation in a single-active-electron model. We analyze the process of "frustrated tunnel ionization" and its dependence on the potential and a variety of laser parameters, such as the intensity, carrier-envelope phase, and ellipticity. Our calculations support current experimental work at Griffith University.
