Laser pulses with a duration of one femtosecond or shorter can be generated both in the Vis-IR and in the extreme UV, but the deep UV is a spectral region where such extremely short pulses were previously not available.
Harmonic concatenation is our new method for the synthesis of ultrashort pulses, yielding record-short deep UV waveforms of only 1.5 fs!
Attosecond Laser Physics
The Attosecond Laser Physics Group aims at an understanding of the physics on the electronic timescale through attosecond spectroscopy.
