title: Time-energy analysis of above-threshold ionization.
abstract: A Wigner-distribution-like function is proposed for analysis of the time-energy distribution of photoelectron emitted from an atom in intense laser fields. For the first time, the time-energy distribution of the photoelectron spectrum in above-threshold ionization is present. The interference pattern in the above-threshold ionization process in laser fields with different frequencies are investigated using the proposed method.
