摘要
System and method for Ultrafast Electron Diffraction (UED) and Microscopy (UEM) configured to image atomic motion in real time with sub-femtosecond temporal resolution. Presented methodology utilizes the interaction of the pump optical pulse with the initial electron pulse that has been gated with the gating optical pulse. The initial electron pulse is generated in the electron microscope by the pulse of auxiliary light. In one case, the pump and gating pulses have attosecond duration and are duplicates of one another. The use of attosecond optical pulse (with frequency spectrum extending over two octaves in the visible and flanking spectral ranges) for optical gating of a pulse of electrons.
