WebIt is known that Maxwell's equations become nonlinear if the effect of virtual electron-positron pair creation is included. The vacuum, thus behaving like a polarizable … WebWe suggest an experiment to observe vacuum birefringence induced by intense laser fields. A high-intensity laser pulse is focused to ultra-relativistic intensity and polarizes the vacuum which then acts like a birefringent medium. The latter is probed by a linearly polarized X-ray pulse. We calculate the resulting ellipticity signal within strong-field QED …
Webvacuum birefringence: A high-intensity laser pulse is focused by an F=2:5 ofi-axis parabolic mirror. A hole is drilled into the parabolic mirror in alignment with the z-axis (axes as indicated) in such a way that an x-ray pulse can propagate along the z-axis through the focal region of the high-intensity laser pulse.
