摘要： A driver (1) for a plasma particle accelerator includes a plasma (10) and laser system(s) (2) that generate first and second pulses. The first pulse (4) has a duration less than the electron plasma period. The second pulse (6) is temporally smooth and has a duration greater than the electron plasma period and less than the ion plasma period. The first pulse generates a plasma wake and the second pulse interacts with the wake to form red and blue-shifted sidebands. The driver also includes a dispersive optical device (20) that introduces a chromatic dispersion to shift the spectral phases of the red and blue-shifted sidebands, to temporally shift them relative to each other, so as to form coincident pulses (22) for generating a plasma wake in a plasma particle accelerator (26).
