Abstract

Low-energy (< 20 eV) free electrons produced in above-threshold ionization have been scattered by an intense optical standing wave (the Kapitza-Dirac effect). At intensities of 1013 to 1014 W/cm2 there is very high momentum transfer between the standing-wave "lattice" and the electrons (Δp1000k). In this regime, the scattering rate approaches the optical frequency, and the electron motion is most easily analyzed by classical mechanics.
