Intense laser light offers new prospects for probing fundamental physics. Laser facilities such as ELI and the European XFEL will give us access to QED processes which cannot occur in vacuum (i.e. without an external field), the most well known example being Schwinger pair creation. I will examine the theory behind, and prospects for observing, a variety of QED processes in modern, short-duration, laser pulses. Examples include pair creation via the Schwinger, trident and photon-stimulated mechanisms, electron scattering and pair annihilation to a single photon.
