Abstract
The concept of a laser-guided e⁺e^- collider in the single-femtosecond and high-energy regime is presented and its feasibility discussed. Ultra-intense laser pulses and strong static magnetic fields are employed to unite in one stage the electron and positron acceleration and their microscopic coherent collision in the GeV regime. We show that such coherent collisions yield a very large enhancement of the luminosity as compared to conventional incoherent colliders.
