Harmonic generation in keldysh-type models

  • F. Ehlotzky
Article

Summary

We shall investigate two models of harmonic generation in the spirit of the Keldysh theory and we shall apply these models to hydrogen, for which more exact data for the rates of this process are available. Although our models correctly describe the angular distribution, the intensity dependence (in the perturbation regime) and the selection rule for odd harmonics, they badly fail in their predictions of the correct order of magnitude of the rates, in particular, of the formation of a plateau. These latter findings disagree with the results of a similar model calculation by Beckeret al. for a δ-function potential.
