摘要：
An injector and accelerator is analyzed that uses three collinear laser pulses in a plasma: a pump pulse, which generates a large wakefield (greater than or equal to 20 GV/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 wakefield for acceleration. Particle tracking simulations in I-D with injection pulse intensities near 10(17) W/cm(2) indicate the production of high energy electrons with bunch durations as short as 3 fs, energy spreads as small as 0.3%, and densities as high as 10(18) cm(-3).
