"laser field hurls plasma electrons back and forth nearly speed of light... pulse durations <4 femtoseconds and temporal contrast ratio (between the pulse intensity at its peak and 10 picoseconds before) of 1010... fine control of interaction conditions... preceding laser pulse initiates plasma creation and expansion. Varying time delay after which subsequent main driving pulse fired... control nanometer-range density gradient on plasma mirror surface... usable secondary radiation and particle source"
