ABSTRACT
We demonstrate the generation of 0.4-keV, sub-27 fs electron pulses using low-intensity laser pulses from a Tisapphire oscillator through the excitation of surface plasmon waves on a time scale within the plasmon lifetime. Modeling of the ponderomotive electron pulse acceleration yields electron energy spectra that are in excellent agreement with the observed ones. Our work opens a doorway for time-resolved experimentation using low-power, high-repetition rate laser pulses.
