We consider the absorption of probe photons by electrons in the presence of an intense, pulsed, background field. Our analysis reveals an interplay between regularisation and gauge invariance which distinguishes absorption from its crossing-symmetric processes, as well as a physical interpretation of absorption in terms of degenerate processes in the weak field limit. In the strong field limit we develop a locally constant field approximation (LCFA) for absorption which also exhibits new features. We benchmark the LCFA against exact analytical calculations and explore its regime of validity. Pulse shape effects are also investigated, as well as infra-red and collinear limits of the absorption process.

One-photon pair-annihilation in pulsed plane-wave backgrounds
A locally constant field approximation for one-photon pair annihilation in plane-wave laser backgrounds is derived, benchmarked, and shown to give negligible event rates in realistic laser-plasma and QED-cascade scenarios.

A uniform locally constant field approximation for photon-seeded pair production
An improved locally constant field formula for laser-driven pair creation stays accurate at lower laser intensities than the standard version, reaching about 10 percent error at intensity parameter 1.25.
