Nonlinear Optical Properties in Vacuum Induced by Intense Laser Light with Axially Symmetric Polarization

Abstract

We investigated the interaction of an axially symmetric polarized light with a vacuum at electromagnetic-fi eld strengths far below the Schwinger limit. Although polarization and magnetization in a vacuum induced by the axially symmetric polarized light are clearly different from those for a linearly polarized light, the number of photons radiated from the vacuum is not very dependent on the light polarization.
