TL;DR: It has been found that for a focused laser beam propagating in free space, there exists, surrounding the laser beam axis, a subluminous wave phase velocity region that Relativistic electrons injected into this region can be trapped in the acceleration phase and remain in phase with the laser field for sufficiently long times, thereby receiving considerable energy from the field.

TL;DR: In this article, Ho et al. reported that the electron can be captured and violently accelerated by the strong-field laser beam field when interacting with an extraintense stationary laser beam, where $Q$ is the dimensionless measure of the field intensity.

TL;DR: A quantitative study of an effect, in which a low-energy free electron is captured and violently accelerated to GeV final kinetic energy by a stationary extra-high-intensity laser beam (Q0 identical witheE/m(e)omegac greater, similar100).

TL;DR: In this article, a short-pulsed laser of TEM (1, 0) + TEM(0, 1) was used to trap electrons in transverse and accelerate them with the longitudinal ponderomotive force at the same time.

TL;DR: It is demonstrated that electrons are trapped well by the laser potential well, and that at the same time the acceleration by the longitudinal ponderomotive force induces the electron bunch compression, which can be compressed to the scale of the laser pulse length.
