  Electron accelerations of the order of $10^{21} g$ obtained by laser fields
open up the possibility of experimentally testing one of the cornerstones of
general relativity, the weak equivalence principle, which states that the local
effects of a gravitational field are indistinguishable from those sensed by a
properly accelerated observer in flat space-time. We illustrate how this can be
done by solving the Einstein equations in vacuum and integrating the geodesic
equations of motion for a uniformly accelerated particle.
