Sentences with phrase «ultrashort electron»

«The work shows how magnetization of nanoscale magnets can be steered by intense ultrashort electron pulses,» said Alexander Schäffer, a doctoral student at Martin - Luther - Universität Halle - Wittenberg in Halle, Germany, and lead author of the paper.

These feature make ultrashort electron pulse trains an ideal tool with which to monitor, in real time, the ultrafast processes initiated by the impact of light oscillations onto matter.

Using tunneling ionization and ultrashort laser pulses, scientists have been able to observe the structure of a molecule and the changes that take place within billionths of a billionth of a second when it is excited by an electron impact.

Electron microscopy and electron diffraction can provide the spatial resolution to image atoms, but filming atomic motions requires ultrashort shutter speeds — the shorter the electron pulses, the sharper the images from the micrElectron microscopy and electron diffraction can provide the spatial resolution to image atoms, but filming atomic motions requires ultrashort shutter speeds — the shorter the electron pulses, the sharper the images from the micrelectron diffraction can provide the spatial resolution to image atoms, but filming atomic motions requires ultrashort shutter speeds — the shorter the electron pulses, the sharper the images from the micrelectron pulses, the sharper the images from the microcosmos.

«Electrons used to control ultrashort laser pulses.»

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very bright, and the photons delivered must have sufficiently high energy.

Among other achievements, his group has used the response of electrons to measure the electric field of a laser's ultrashort pulses and display the waveform, much like displaying a radio - frequency wave on an oscilloscope.
