Electron-positron-photon jets generated by circularly polarized lasers — •suo tang, naveen kumar, and christoph h. keitel — Max Planck Institute for Nuclear Physics, Saupfercheckweg 1, 69126, Heidelberg, Germany
With the next generation of ultra-intense laser pulse with intensities (I∼ 1024W/cm2), pair production and QED cascades can be induced by slow electrons or positrons. The generated pairs are accelerated by the laser fields to ultrarelativistic energy. High quality electron-positron-photon jets can be emitted from the field formed by the two counterpropagating circular polarized laser pulses. By adjusting the relative frequency and intensity of the laser pulses, the direction and energy of the jets can be controlled.
