An electron injected sideways into the focal region of a tightly‐focused laser beam encounters strong field variations in both space and time. Thus, momentum may be imparted to it by the field in the nature of a small number of violent impulses. Results from single‐particle calculations are presented which demonstrate electron acceleration to GeV energies in petawatt beams focused down to around ten‐micron spot size. We conclude that a captured electron moves effectively in phase with the field and absorbs energy from it..
