Quantum effects in above-threshold ionization

G. G. Paulus, F. Grasbon, A. Dreischuh, H. Walther


We report on the relevance of quantum effects in above threshold ionization for low and high energy photoelectrons. High repetition rate lasers are used to study energy resolved electron yields as a function of ellipticity as well as the angular distribution of the photoelectrons. In comparison with theory it is possible to identify quantum effects.
