Abstract
When an atom or molecule is exposed to a strong alternating electric field, such as from a
femtosecond pulsed laser, the electron can be tunnel ionized and subsequently driven back to the
parent ion in a three-step process called electron recollision. We report on a novel attosecond
study of electron recollision using sub-cycle XUV pulses to ionize noble gases dressed by an
infrared field of sufficient intensity to drive recollision, this technique is dubbed the Strong Field
Simulator. In this experiment, the XUV pulses serve to replace the ionization step while the
infrared field still accelerates the electron and drives recollision. Isolating the ionization step
from the other two, we can select the moment of ionization, and correspondingly the electron's
quantum trajectory, opening new possibilities for studying electron recollision.
