Double-Slit Light Diffraction in Strong Electromagnetic Fields — •Ben King, Antonino Di Piazza, and Christoph H. Keitel — Max-Planck-Institut für Kernphysik, Saupfercheckweg 1, 69117 Heidelberg

In [1] the vacuum-polarisation effects of change in ellipticity and polarisation of a laser probe beam passing through an ultra-intense standing wave, were calculated. We further develop these results to increase the measurable polarisation and ellipticity, by calculating diffraction effects from the double-slit-like setup of two parallel and off-centre, gaussianly-focused, strong field waves propagating against each other. We move towards a measurable set-up through calculations of the off-axis effects on a focused probe beam, allowing alternative detection of these vacuum effects.
