Theory of probing attosecond electron wave packets via two-path interference of angle-resolved photoelectrons

POSTER

Abstract

We study theoretically the electron wave packet generated by an attosecond pulse train (APT) which is probed with a time-delayed infrared (IR) laser pulse. The APT creates an excited state and a continuum electron wave packet. By ionizing the excited state with an IR, a delayed new continuum electron wave packet is created. The interference of the wave packets from the two paths, as reflected in the angle-resolved photoelectron spectra, is analyzed analytically.
