One-photon annihilation of an electron-positron pair in the intense pulsed laser field

We theoretically investigate one-photon annihilation of an electron-positron pair in the intense pulsed laser field. It is demonstrated that a process of one-photon annihilation is possible only with emission of a large number of the wave photons within the range of the optical frequencies of a laser field. Itpsilas shown that a probability of the one-photon annihilation is optimal for the intense laser field.
