Abstract

In the present work we analyse the nonlinear, nonlocal response tensor describing optical second-harmonic processes in centrosymmetric free-electron-like bulk metals with a flat surface. On the basis of the classical infinite barrier (CIB)-model and the Boltzmann equation in the relaxation time approximation we present new analytic results for the fully nonlocal nonlinear response tensor. Via numerical calculations the nonlinear, fully nonlocal response tensor's dependence on the fundamental frequency is discussed and compared with that of the near-local (hydrodynamic) response tensor. Finally, the significance of the contribution to the nonlinear, nonlocal optical response stemming for single-particle excitations, i.e. Landau interactions, is considered.
