We study the $2\ensuremath{\rightarrow}1$ process of electron-positron pair annihilation to a single photon in a plane-wave background. The probability of the process in a pulsed plane wave is presented, and a locally constant field approximation is derived and benchmarked against exact results. The stricter kinematics of annihilation (compared to the $1\ensuremath{\rightarrow}2$ processes usually studied) leads to a stronger dependence on the incoming particle states. We demonstrate this by…

The process of electron-positron annihilation into two photons in the presence of an intense classical plane wave of an arbitrary shape is investigated analytically by employing light-cone
We study the photon trident process, where an initial photon turns into an electron-positron pair and a final photon under a nonlinear interaction with a strong plane-wave background field. We show

It is shown that, if the laser facility provides a total power above 20 PW, it is possible to trigger not only a QED cascade but also pinching in the produced electron-positron plasma, which can provide extreme conditions for probing and exploring fundamental physics of the matter and vacuum.
