Abstract
Wakefields generated by a tightly focused laser beam (w0 ≪ λp ≡ 2πc/wp) are characterized by a region of total electron cavitation near the head of the laser pulse, followed by a highly localized region of high electron density. The accelerating field maximizes at a spot size significantly less than λp. The focusing fields are generally larger than the accelerating field, and exhibit complex phasing detrimental for accelerator applications. Modeling of these wakefields is facilitated by the ponderomotive guiding center algorithm
