Abstract

We argue that long-range photon-photon attraction induced by the dipole interaction of two electron-positron loops can lead to "vacuum self-focusing" of very intense laser beams. The focusing angle θF is found to increase with the beam intensity I as θF ∼ I4/3; for the laser beams available at present or in the near future, θF 10-10 - 10-7.
