Enhanced Subthreshold e+e- Production in Short Laser Pulses


Enhanced Subthreshold e+e- Production in Short Laser Pulses

Titov, A. I.; Takabe, H.; Kämpfer, B.; Hosaka, A.

The emission of e+e- pairs off a probe photon propagating through a polarized short-pulsed electromagnetic (e.g., laser) wave field is analyzed. A significant increase of the total cross section of pair production in the subthreshold region is found for decreasing laser pulse duration even in the case of moderate laser pulse intensities.
