Phys. Rev. Lett. 79, 2682–2685 (1997)Electron Injection into Plasma Wakefields by Colliding Laser PulsesReceived 6 February 1997; published in the issue dated 6 October 1997 An injector and accelerator is analyzed that uses three collinear laser pulses in a plasma: an intense pump pulse, which generates a large wake field (≥20GV/m), and two counterpropagating injection pulses. When the injection pulses collide, a slow phase velocity beat wave is generated that injects electrons into the fast wake field for acceleration. Particle tracking simulations in 1D with injection pulse intensities near 1017W/cm2 indicate the production of relativistic electrons with bunch durations as short as 3 fs, energy spreads as small as 0.3%, and densities as high as 1018cm-3. © 1997 The American Physical Society URL:
