Chair for Laser Physics

Welcome to the website of the Chair for Laser Physics!

At the moment we work in three main branches of research that combine the topics of laser physics, quantum, electron, and nano optics, strong-field and attosecond physics, plasmonics and solid state research. We investigate the wave and particle properties of electrons in ultrafast processes in and at nano objects; we develop new particle traps to create quantum optical systems in order to build a quantum electron microscope; we use laser pulses at photonic nanostructures to look into novel concepts for particle acceleration.

The main part of our laboratory is centered around light-matter interaction on fastest time scales, namely the femtosecond and attosecond time scale  (1 fs = 1 millionth of a billionth of a second, 1 as = 1 billionth of a billionth of a second). This allows us, to put it a bit more abstractly, to work towards understanding und utilizing photon-electron coupling in various systems. A part of this is based on highly advanced methods to control electrons, often with light fields, which requires building new laser sources and amplifiers.

Our chair and FAU Erlangen are founding members of the Max Planck Graduate School of Photonics. Apply here and until December 15th, if you are interested in a master's degree or doctoral training at one of the world's leading working groups in the broad field of photonics.

Professor Hommelhoff was elected to the DPG Parliament, in the course of the DPG Board of Directors election in 2018. The DPG, the German Physical Society, is the largest physical society in the world with over 60,000 members. Its presidents included Albert Einstein, Fritz Haber, Hermann von Helmhol...

After successfully defending his thesis "Ultrashort pulsed fiber lasers at 2-µm wavelength for dielectric laser acceleration of electrons and optical parametric amplification", Heinar Hoogland may now call himself Dr. Hoogland -- congratulations!

We describe an electron microscope whose electron emitter is operated with femtosecond laser pulses and a whole series of experiments with this device around electron acceleration using photonic structures in a publication that has just appeared in the Journal of Applied Physics. Apparently the arti...
