12. From Eq. (1) and the form of Gn, it is easy to see that since Δ→ is field dependent, harmonics can be generated even if j→ is linear in the fields. However, usually v→ must be sufficiently large (nonlinear) to result in a finite Δ→. We see also from Eq. (1) that although the latter does not alter significantly the magnitude of the radiation, it can greatly affect the angular distribution of the harmonics.

14. The theory of scattering of a linearly polarized light and/or oblique incidence within the present model is considerably more involved, as the electron motion in the laser field has then an axial component. There is thus a finite-depth interaction layer. Nevertheless, if the latter is sufficiently thin, an effective surface current can still be constructed.
