Many processes in our everyday life follow their statistics according to a Poisson distribution. In fact, typical laser sources also behave in this way. For pulsed lasers, this graphically means that the number of photons in a laser pulse fluctuates around a certain mean value (with the root of the ...

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...

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...
