Light-Based Chromatic Aberration Correction of Ultrafast Electron Microscopes
Original language description
We propose and theoretically demonstrate a technique that allows one to compensate for chromatic aberrations of traditional electron lenses in ultrafast electron microscopes. The technique is based on space-and time-dependent phase modulation of a pulsed electron beam using interaction with a shaped pulsed ponderomotive lens. The energy-selective focal distance is reached by combining the electron temporal chirp with the time-dependent size of the effective potential, with which the electrons interact. As a result, chromatic aberration can be reduced by up to a factor of 7. This approach paves the way for advanced transverse and longitudinal wave front shaping of electrons in free space.
