A large area of ultrafast physics is all about the motion of electrons in strong pulsed laser fields on the time scale of femtoseconds (1 fs = 1 millionth of a billionth of a second). If femtosecond laser pulses are now sent to extremely sharp metal tips, extremely short electron pulses are produced...

The second now again public defense at our chair after some years - and also at this one everybody was not only enthusiastic about another outstanding lecture, but also about the wonderful atmosphere: Tobias Weitz defended his thesis with waving flags -- congratulations! For all who don't know him p...

SCHOOL ON THE FRONTIERS OF LIGHT: Photonics with free electrons -- this summer school will take place at ICFO close to Barcelona at the beginning of July. Apply  here by May 14.

Attosecond physics, also called strong field physics, is based on the fact that electrons are emitted from something on the attosecond time scale and are accelerated thereon in the intense optical field. Some of the electrons are even driven back and collide with the body emitting them. For about 30...

Another highly interesting ACHIP collaboration meeting is behind us - this time in Stanford and with the hottest results from there and from Erlangen. Was this really the last meeting? Unfortunately, after more than seven years of generous support, the Gordon and Betty Moore Foundation cannot contin...

For more than ten years, we and other research groups worldwide have been working on strong-field physics on solids - which until now could only ever be observed on nanometre-sharp needle tips. In terms of the driving optical wavelength, these tips are zero-dimensional objects. We wondered if we cou...

After several Corona-related years without a public part, Philip Dienstbier was able to defend his dissertation this time - for the first time with us again - with an audience. So, finally, not only the three examiners were able to follow another outstanding defense lecture - congratulations, Dr. Di...
