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.

After successfully defending his thesis "Ultrashort pulsed fiber lasers at 2-µm wavelength for dielectric laser acceleration of electrons and optical parametric amplification", Heiner 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...

For three years, we have been part of DFG priority programme "Quantum Dynamics in Tailored Intense Fields" (QUTIF) with a joint project together with the groups of Prof. Dr. Thomas Fennel (U Rostock) and Prof. Dr. Matthias Kling (LMU Munich) -- now our joint application for renewal has been positive...

This year's theme of the International Symposium of Advanced Photonics was Attosecond Science. Three of our group members had been generously invited to participate in the symposium taking place biannually close to Hamamatsu, Japan, at the beautiful Hamana lake. Please find more details here.

The preview version of an invited review article on attosecond physics phenomena at nanometric tips has just appeared. While the final version will contain a number of additions and minor changes, we follow Journal of Physics B and advertise this non-edited and non-final version already here. The ar...

Which are the next walls to fall? The aim of the Falling Walls Foundation is to remove the great hurdles of our time, such as the ubiquitous scepticism about founding a start-up - especially in Germany. Within the framework of the workshop "Young Entrepreneurs in Science", doctoral students were int...
