Focussing on null fields as simple models of laser beams we discuss the classical relativistic motion of charges in strong electromagnetic fields. We suggest a universal, Lorentz and gauge invariant measure of laser intensity and explicitly calculate and interpret it for crossed field, plane wave and vortex models.

Resonant production of millicharged scalars in $k^2>0$ electromagnetic wave background
Resonant exponential growth of millicharged scalars in k²>0 electromagnetic waves is obtained by mapping the Klein-Gordon equation to the Mathieu equation, yielding new constraints on such particles.
