We propose a new catalysis mechanism for nonperturbative vacuum electron-positron pair production, by superimposing a plane-wave x-ray probe beam with a strongly focused optical laser pulse, such as is planned at the Extreme Light Infrastructure (ELI) facility. We compute the absorption coefficient arising from vacuum polarization effects for photons below threshold in a strong electric field. This setup should facilitate the (first) observation of this nonperturbative QED effect with planned light sources such as ELI yielding an envisioned intensity of order 10{sup 26} W/cm{sup 2}.

- Extremely high-intensity laser interactions with fundamental quantum systems (2011, background): “A first possibility to facilitate the observability of pair creation in a standing optical laser wave is to superimpose an x-ray photon (or any other high-frequency component) onto the high-field region (Dunne et al., 2009; Monin and Voloshin, 2010; Schützhold et al., 2008).”
