Abstract

Summary form only given. In this paper, we show that the argument about vanishing THG breaks down under relativistic conditions. We consider the motion of a free electron in an intense laser field of wavelength λ. For field strengths of the order of mc2/λe, which for λ=1 μm corresponds to an intensity of the order of 2×1017 W/cm2, the electron is accelerated to relativistic velocities in a single optical period, and thus the excursion of the electron from its equilibrium position occurs over a distance of the order of λ. Under such conditions, the radiation emitted by the electron cannot be described within the electric dipole approximation, and in fact cannot be well described by a multipole expansion for a finite number of terms. We instead calculate the intensity of the emitted radiation through the use of the Lenard-Wiechert potentials.
