Laser enhanced field emission — •Simon Däster — ETH Zürich

We report a setup to create femtosecond long electron pulses in an electron microscope. A commercial scanning microscope has been adapted in order to amplify a static electric field with a concentrated femtosecond laser pulse. It is shown how to measure this small electron beams. Furthermore, new research fields are indicated where to use this technique for an enhanced observation of electron dynamics.
