| Research Abstract |
We have demonstrated single-shot measurement of electron diffraction patterns for a single-crystal gold foil using 340keV electron pulses accelerated by intense femtosecond laser pulses with an intensity of 2 10^<18>W/cm^2. The measured electron beam profile is faithfully reproduced by the numerical simulation of the electron trajectory, providing evidence that the electron pulse spontaneously expands in time owing to the velocity spread produced in the acceleration process, but is not distorted in an irreversible nonlinear manner. This study shows that the laser acceleration is promising for the development of pulse compression methods for single-shot femtosecond electron diffraction.
