Attosecond X-ray Science

We generate attosecond pulses in the soft X-ray spectral range (200 eV and higher) since such pulses permit probing the flow of energy at the absorption edges of atoms inside molecules and materials.

Extreme Photonics

Extreme photonics is concerned with the interaction of intense light fields with matter. For instance, we investigate, and use physical phenomena such as filamentation and solid harmonic generation to study X-wave generation.

Quantum Dynamics

We study electron dynamics to determine whether and how a molecule dissociates and how a chemical reaction occurs; electrons sustain the energy flow in human vision or of our nerve system, and they determine whether biological life ends.

Ultrafast Laser Science

Our focus is on the generation of mid-infrared few-cycle and CEP-stable intense sources at high repetition rates beyond the kHz, thereby pushing the limits of average laser power.
